Sorry to hear that Pink, yes it's bitch-expensive here. I too have a low level of calls as I am horribly picky in my ads and spell out why certain people are not welcome to call me.
I often get 2 calls a day, but I'll usually get a nice well paid job from one of them. Any bunch of minor, cheap and cheerful, quick gigs on top of that is all beef gravy eg from £40 upwards. Often it's 1 call I job which suits me. It's not the number of calls that counts, it's the booking ratio. I wonder why they don't stick?
-Eros and Cherry girls seem to have been on the decline for many years. Personally I don't touch them.
-Slixa is mentioned on several threads here as being a 'waste of time', I also don't think it's very well know in the UK.
-My computer firewall has blocked Tryst as, it says 'The website tried to negotiate an inadequate level of security...it uses security technology that is outdated and vulnerable to attack' So I can't comment on that site.
I agree with Amy....I wouldn't fret about £300 girls, we charge what we like. My colleague charges £150 per gig and now owns 3 homes in Mayfair.
Agree with all of this. I use cherry girls and it's nothing giving me much (in fact, I do not advertise on adultwork anymore and basically I do not get timewasters anymore, but the ones I get are always from cherry girl

. I know other people experiences with slixa and eros - they get basically nothing.
Op. Don't start with 250ph if you want to relocate back in london. You have to raise rates over time.
I recently raised my rates to 250ph in london and I'm still busy and honestly still can't believe I could do that. It seemed unreachable for me even though I started working in London few years ago on 180-200ph.
First of all there are sites for advertising but mainly look into international directories because that's where all the international clients look. I would suggest buying banner advertisement, advertise like crazy on twitter posting your photos 2 times a week, try to engage there, hire person for seo, seriously because without this you would get lost. My 30% of traffic comes from google, this means clients google and you have to be found on google.
I have friend which is very busy working on 250ph rate in london, working monday-friday. What she told me - she used to spend 1k a month for advertisement. Because that's how you mainly get bookings - you have to be visible, you have to spend to earn.
All the time I get slower, I start panic and buy another advertisement

I do have banner ads, good twitter presence, I have very good seo, I have featured ads in few sites that work for me.
Also everyone want to be 'high class escort' but you have to understand that usually the ones who charge much, provide very niche services.
Also they see less clients and usually have lower personas somewhere else.
So also do not forget to calculate what's your goal. and how much clients do you want to see and how much clients do you think you will get.
Like is it better to charge 300ph and get 2 bookings a week or is it better and more approachable to charge 200ph and hopefully get 3-4 times clients than that.
