[...] but i do know his bank account name and account number! [...]
This guy has been ripping you off, trying to blackmail you (and scam you) and has been REALLY breaking the law by doing what is called "controlling prostitution for gain" (this is jail-time serious breaking the law stuff, especially now when the media is full of scary stories about pimps and traffickers and whatnot; those stories might not be based on much reality but the fact is it has resulted in a lot of police departments being extra-attentive when it comes to complaints about "controlling prostitution for gain" AKA pimping/finding clients for girls) - so basically, he's a massive stupid criminal.
With his bank details, the police could definitely track him down. It might be worth investigating making a complaint with the police about him. You might want to contact a sex work outreach group near you first, for advice on this sort of situation as you understandably don't want to make yourself vulnerable in any way (although you have NOT broken the law in ANY way by working as an escort).
He sounds horrible. If nothing else, it might be a good idea to post any information (AW nickname, other nicknames, phone number(s) etc) in the Warnings section of this forum. You never know - other girls might know about him. It sounds like he is a practiced predator of naive/new young women.
(Please also make sure you never give out account names or passwords in emails to ANYONE, and don't send money to anyone, either. You
never need to do these things for legit people/companies and it's much better to come somewhere like here first and ask for advice from other people who might've been through similar stuff before going ahead with giving passwords and/or money away. We have plenty of time to help!

Oh! And regarding your own advertising - head over to the main site here: http://www.saafe.info/ and hover over the "Information for Escorts" menu item to see the list of topics; choose "Where to Advertise" in the Business section to find a huge article written by the famously successful ParisB - it's got tons of great ideas in it! No one directory is perfect for every escort but you can do lots of trial-and-error to find your perfect marketing areas.
The rest of the main site has loads more info on everything to do with sex work, too, so do browse around whenever you get time.
