I can give you the details I have. Out of seven e-pubs I queried in early February for a raunchy m/m space opera romance, two danced around an offer. Both looked great. I did what many e-pub writers are told not to do, and contacted an agent.
An amazing, high-powered, very exclusive agent with decades of experience in romance and sf&f, who is normally not open to public queries. I basically said "I know you don't really rep m/m, and that you may not have a relationship with these publishers. I'm in a bind because of a very rare, very tricky situation that is entirely my creative fault, and I'm willing to pay an expert 15% to help navigate through it all. It won't be easy money. Feel free to drop me, if this is too crazy. Frankly, I'm hoping you eventually fall in love with my mainstream fantasy writing, and you might be my agent for real. But for now, I need help with this project."
A month later, I'm signing paper copies of my contract with Loose ID, one of my dream e-publishers. Next week or so, I embark on edits, which are going to be brutal and necessary. Not bad for a book I started in March of 2011, after realizing I didn't want to edit other people's smut - I wanted to write my own.
