It's really, really tough to market fiction as an indie. Especially if you don't have a platform. For my memoir I have the pickup scene behind it. Non fiction sells way better than fiction overall, unfortunately, as I think there's a lot to be learned from great fiction. I'd say go to the Kboards writer's cafe and talk to people there.
As far as I know most indies are doing free give aways, 99 cents books, and writing series. Series are the way to hook the reader and sell more books.
For getting an agent there is software I used called Query Tracker.
