Just stumbled upon this: http://www.pcgamer.com/humble-bundle-launches-multi-platform-publishing-and-funding-program/?utm_content=bufferde856&utm_medium=social&utm_source=facebook&utm_campaign=buffer_pcgamerfb
Humble Bundle dips into publishing business. They claim they are picky about the games they are going to publish, with focus on quality. Obviously, they are accepting submission, here's the link: https://humblebundle.wufoo.com/forms/mpf6fag1x0rhg5/
IMHO this could be useful for securing funding. They also have experience with porting games to other operating systems, pretty sure they made some conversions in house.
