This is only a possible lead as I don't know how it works in this country, but if you're in London (I don't think there are any elsewhere in the UK), you could look into hostess clubs. I got into escorting via a club in Copenhagen, it was nice that I got to talk to customers before even thinking about going out with them, and it sounds like it would be ideal for you. Customers buy overpriced drinks which allow them to spend time with you and you get a commission. You can then try to get tips and if you like, make your own arrangements with him.
