Thanks so much for more wonderful replies! It's great to get such a range of opinions - as nice as a unanimous answer can be, this is risk management without a clear answer, but each and every one of you is a very useful influence in helping me come to my final decision.
I know my home setup isn't ready to host. I don't think it's impossible, though, for a select group of clients. As a general rule, I'll be hoping for repeat business rather than lots of new guys - I know you can never trust a client as a person and have to keep things professional and business - but I'd hope to be able to be quite selective about who I allow to visit me at home.
I'm definitely leaning more no nonsense in my profiles and communication than I was before - I was afraid it would put people off, but I think it's only really going to put off idiots and time wasters.
Oh, it'll take me a long time to develop instincts for time wasters, I always find I lack a woman's eye for people and can be quite trusting - but I've ended communication with easily half of the men who've contacted me so far, for one reason or another. I'm not just going to meet anyone - I'm lucky enough to not need this income to survive.
I stepped quickly back from my age limits. I'm willing to accept that guys over 50 may surprise and delight, dubious as I feel. I'll still probably do checks on very young looking guys, I'm happy to meet anyone 18 and over but need to be careful of course.
That's all great food for thought, much I'd already considered but great to read it all laid out so well. The low volume thing is something I should be more clear about on my profiles, up front. And the sideline for guys wanting to dress is definitely a possibility - I'm quite fussy about getting good stuff so while much of the latex that forms the backbone of my look is made to measure and I'd never let another touch it, in time I'll aim to have an expansive enough collection of other items that dressing sessions might be a good idea!
Sticking to my prices is already an area I'm failing in. When I started, I set them moderately, after looking at some of the local competition. I quickly decided based on volume of contact and pride to not sell myself cheaply and to be sure I restricted this to men who actively want what I am, not just guys who can't afford a real woman. I upped my prices significantly based purely on my own estimation of the value of my time, still not to real high-class levels but about on a par with most women. Contacts continued, I thought all was fine. About a week and a half ago, I felt about ready to start, edited my profile to say as much and sent messages to many who I'd told I wasn't yet available and who'd asked for updates when I was. Yesterday, over a week on, I started to worry that I was going to get no business. Now that was silly, despite being supposedly ready, I'd been asked about my availability multiple times and always given a very prohibitive reply since I had a lot planned in my own life this last week or so. Also, I never WANTED high volumes of contact. And, I still hadn't sorted a work phone, it's arriving on Monday and I'll be able to put it online to hopefully make me more approachable. Anyway, when I switched to outcall only, I also panicked and reduced my fees, in a way I already don't feel comfortable with.
Anyway, I'll be okay. I've already got 2-4 guys who seem some degree of serious about booking an outcall or hotel meet - some I've quoted the new rates so may have to meet at those the first time even if I put my prices back up. Two of them were interested before I reduced the prices, and one in particular seems very serious, with me having been the time waster so far in our correspondence, he would have met me days and days ago,.or this evening, if I'd had the gumption and had been free.
Anyway, yes, I just need to lean into my niche and be sure of what it is. I'm young and more physically fit than a great many crossdressers, I'm confident and a bit dominant which isn't entirely common among dressers (not uncommon either, of course) and while pre-op girls have a very significant appeal over me in their bodies, those men who want somebody as feminine as possible whilst being fully functioning and virile are likely to choose me. And of course the reasonable wide range of fetishes I'm happy to work with and the pro-Domme stuff is a very clear niche in which to market myself. Guys wanting to book in advance DOES seem to be the norm, not always, I've had a fair few same day requests but I think most of my work will be booked in advance - pros and cons to that, it'll make planning easier and could allow for a few meets to be stacked together in an afternoon at a hotel, but definitely suits incall work better than touring, I think.
Working out a way to direct guys here without giving my actual home address is a very good idea - there's no street name or number visible anywhere so I might be able to avoid my address ever being given out - I mean it could always be figured out from Google maps I'm sure but I do think I could give useful directions without giving too much information.
I do have something of a buddy but she's very slow at responding to me these days - interested in the work and concerned about my safety, but not sure she's an entirely reliable person for a safety call - although that's not fair, the only time I ever called her in an entirely unrelated emergency she was incredibly quick to respond and switched right into crisis mode. She's older, wiser, a bit maternal and has never met nor know the names of any of my friends or family, just an old fuckbuddy who I trust very much.
Thank you all so so much for continuing to give me new things to mull over and lots of useful data points in making my decision. For the time being, I'm going to stick with the outcalls since I've immediately seen an uptick in interest since disabling incalls - I'll make a point of calling the local chain hotel (Premier Inn - I know it's not great but it's that or a guesthouse or pub) and ask about their situation with key cards to get out of the lobby. I know there's no lift, I think it's only 2 or 3 floors - but that would be a huge thing to know, if I can book a room, get dolled up and have a guy come right to my door, this'll all be fine and dandy, I've implemented a policy to take the hotel room cost as a bank transfer when I take the booking, so I can't end up out of pocket. If that isn't the case, I'll have to reconsider. I'm definitely feeling that I'll eventually do incalls, but whether I advertise them or allow first time clients to have them is up for debate, and either way, I'll need to get the home security up to scratch.
Thanks so much for all your help and patience!
