I recently went independent too, and I'm doing really well, so I'm sure you can do it too! Make sure you advertise as many places as possible, there's a great article on this forum on where to advertise. That said I have been relying just on adultwork for a while, and it is working really well for me at the moment!
Make sure you have some nice pics, do the AW interview, have some decent prices, start lowish to get some feedback, and when you start getting regulars you can work your way up!
Edited to add: You have to spend money to make money! Put your phone number on AW, a lot of guys don't bother to send emails, and put yourself as available today. Make sure you have a private gallery, that will earn you credits that you can use to display your phone number, and use the available today feature.
