I'm not sure if I should post this here or in the illustration section since my question deals with both. I've been pretty silent on the boards lately since I've been pounding the pavement, so to speak, for new work and then doing said work. One of those things being a new ebook I'm illustrating for a new company You Tell Me Stories. They're doing some really cool stuff. I've really enjoyed the project and we're now in discussions for another book with the possibilities of getting royalties.
I've illustrated two traditional picture books, so I understand how advances and royalties work there, but I'm just not sure with an ebook. What is a typical percentage for the illustrator? What about an advance? Has anyone worked with a flat fee up front and a lower royalty rate?
I am stepping into this brave new ebook world with nervous first steps. Thanks for any advice and help you wonderful people can offer.
