Maybe Andrea Höst could highlight her experience if you asked her via Goodreads message, as she isn't on LJ? She does have some awesome Julie Dillon covers, she always offers her books as POD, too AND she did - from what I understand - the work on her stockphoto covers (for And All the Stars and The Touchstone Trilogy - the current covers) herself.

Also, shouldn't the BVC people have some singular experience with that. Oh right, and since I see MSW posting below, she did get those spiffy covers for her short stories.

Another person who offers ebook conversion is independently published author Moriah Jovan (no idea how long her waitling list is). I can personally vouch for the beauty of her ebooks at least. http://b10mediaworx.com/b10mwx/

I bet this link will put me in the spam folder again, heh.
