I'm in London.
The thing is, how I do things probably won't be of use to you because we're all individuals with different ways of working. What I will say is that it is your attitude that is key, not just looks or service, so stop concentrating on what other high end escorts look like/their photographs. Look at what they're saying/what experience they're offering and their marketing, that's what will bring you in a particular clientele, although to be fair, so many of them write such pretentious twaddle that it will be an excellent guide of what not to write. The most important thing to concentrate on is what makes you you - you are unique, this is your main strength and selling point. Establish your boundaries and your offer and stick to it. Don't try and be something you're not. Sometimes, it's not better to fake it until you make it. Just be yourself.
I insist on government-issued ID or work credentials plus references as this approach screens out a lot of time-wasters and hagglers. Be advised this approach might well will bring you less clients, and not every high end escort insists on screening in this way, so don't feel you have to do this. I am now in the position where I am not really looking to take on new clients anyway, so how I screen is somewhat redundant.
Lastly, I don't mention I have an MA but it is clear from my website and blog I am well-educated. I do not advertise as high end, high class or use such ridiculous terms as courtesan, luxury, elite or VIP because I feel the type of client who would be googling these keywords wouldn't be someone I want to meet, nor would he want to meet me! He would be expecting a Belle de Jour type which I most certainly am not!
Will look for the thread Amy mentions
