"Busy surgeon has many great ideas for science fiction, historical fantasy and adventure novels, wants to pay a co-author to actually flesh out the ideas and outlines into complete novels..."

This busy surgeon is advertising on elance for a ghostwriter, and I'm sure he (it's got to be a he, surely) will get lots of offers. I'd be more interested in writing the story of the busy surgeon who dreams up science fiction, historical fantasy and adventure while he's hacking away in the theatre.
Or perhaps I could pitch an "alternative reality" novel where a writer gets a job as a busy surgeon? I reckon I could "flesh out" as well as the next guy, given the right instruments, and someone to catch me when I faint.
