Hi guys,
I did suggest Good Shepard http://www.goodshepherd.games to you a while back and I still feel that they would be most helpful in publishing your game.
I have mentioned Autonauts to Paul Hanraets and he thought it looked interesting. Partnering with Good Shepard would allow you to work on the development of the game and not worry about the difficulty of financing it. They have a great track record and lots of resources that would help you.
I hope you will reconsider submitting it. Give it a shot. What do you have to lose?
Best of luck guys,
