You could put up an ad in Seeking/Offering here, at least for starters?

As far as 'cold calling' goes, we had a thread a while back which I can't remember the name of, but it concerned the odd emails (inevitably via AW) everybody must occasionally get from people asking about doing 'duo' work and the general consensus was that they weren't especially welcome - it's an automatic block for me just as the ones from 'male escorts' are, but then I don't see women or couples even for money, so I'm certainly not going to roll about with them for free .

Maybe write something on your ads/blog about looking out for a flatshare? From what I've seen, more ladies than you might think read other's .

Not if you're both NOT working there at the same time.

I thought so.  I do hope they change this soon. It's just so much safer and more pleasant to have someone else there (that's on the same page as you).

In the few duos I've done over the years I contacted the girls with the proposal some replied some didn't, I had one bad experience but the others were great and am good friends now with one girl. I picked the same way clients would really, age, experience, feedback etc. x

I found mine in the spam section on Saafe. 

Have a chat first and if all goes well, meet up for a coffee

Duo's can be quite lucrative especially during the Xmas season. I think I had about 4 or 5 duo bookings in December.

 - Teaming up with someone who offers a different/niche service than yourself can be very beneficial

 - Find someone who shares the same working style as you  i.e you might  accept bookings from 12 am whereas she might accept bookings from 8 am

 - Find someone who shares the same values as you i.e your duo partner might insist on sharing a room when you go touring whereas you might prefer your own space. I know I do!

I am not sure how prevalent twitter is in the UK, but for me it was/is a gold mine for all my duos and group sex bookings!
You can connect with some other SW, guys see you flirt with them and obviously get turn on...and duos!

And in my experience it's worth finding a duo partner similar to you in age and type. Men often have a 'type' so say you are 40 he might not feel comfortable in seeing a 20 year old or if you are a size 12 he might not be into a BBW (or vice versa).

It's really important to have similar values too. If they are the get them in, cumming and out as fast as possible type and you are more laid back and build up slowly so they get their full hour of action it won't work. You need to be sure their idea of security is the same and figure out where you are working. They might say yes to someone you wouldn't and if you are working at your property they might be less fussy in their vetting. Similarly if you are anally tidy or insist on good time keeping working with someone who is messy or always late can be a pain. 

If you're more a cute  girlie type and she is outrageous porny type it can be great fun as a contrast for the client, but it could also be hard work to work together especially if you feel they are taking over, equally if you think she is holding back and not pulling her weight in bookings.

Also, you have to be mindful a client might go for them more than you so you mustn't get stabby feelings if you feel left out, equally if a client is more into you and ignores the other woman it's awkward. Be aware one of 'your' clients who meets her may decide to see her the next time alone and however much your head wants to accept this it can feel hurtful.

If you meet someone agree to do one booking together to see how it goes. Don't start promoting her on your website or getting photos together straight off.

Listen to how she talks about other escorts- if she is gossipy, bitchy or gives away other's real names etc then remember she will do the same about you!

Talk a lot first, talk how you imagine bookings going- we all have our routines, even if they are subconscious and it can feel a bit weird when working with someone else for the first time.  Keep talking, be honest (but not unkind) after a booking. Like everything communication is key and don't be scared to say sorry, it's just not working for me.

Not trying to put you off, just some advice and things to be aware of and saying that I have worked with some terrific women over the years, it can work!
