Welcome uk_emmy
There's a wealth of information on the forum threads and the main site.
My first experience of escorting was many years ago working for an agency doing outcalls only.
Last year I started independently as an escort by creating an Adult Work (AW) profile, offering outcalls and then began offering incalls in London hotels several months later.
Recently I had my own website developed and started advertising in other areas (still online) other than AW.
I only work occasionally as it's more for extra cash rather than main income.
I'm not the best person to give advice on starting up and I'm pretty sure some of the more experienced ladies will be along soon to offer you more comprehensive advice.
Happy reading and feel free to ask away if there's anything specific you want to know
