RESEARCH RESEARCH RESEARCH!!! make sure you look in to all options ie independent, agency, parlour. be absoloutly sure you are comfortable with the choice you make and without a doubt know you will walk away if it feels shit once you start. Dont get scammed by assholes who want your money up front (escortopia etc...).
I have spent as much time as possible looking at directory sites, forums, other ladies websites, all sorts of things to try to know what my limits were and what i was prepared to do. Im still "green" and expect to make mistakes but at least i know what im getting myself in to and im not sure everyone always does. i certainly didnt watch belle de jour and base my expectations on that!!! lol
Cant comment on the hubby stuff because i dont have that issue to think about.
good luck.
