If you only want part time as you escort in the evenings look for something that doesn't start too early as if you have a late outcall it could mean you not getting enough sleep.
I cant suggest jobs as such as I don't know what training you have or what you are qualified to do but if you are on about normal menial style jobs then Toys R us do flexi hours as do Asda, Tescos, Mothercare and all the big name take a ways. You want mother hours. Between say 9 and 3 so you don't have to get up too early yet are home in time to rest and get ready for evening outcalls.
