Hey Lorrainne,
I work for a high class escort agency too. When I started escorting (5 months ago) I wasn't really into AW or working as an indie. If you ask me now, I am 100% for this.
I had only 2 booking with the agency in 5 months. Usually they send me messages to ask me if I am available very late in the night (1-3am) and I would never work at these hours.
I am on AW since then too and I have a lovely profile, 30reviews so far, and a great amount into my savings account until now - doing this as a part-time thing.
My advice: go indie!!!! I know it seems difficult ( it is at the beginning) but it is really worth it.
