Just acquired the Steam Greenlight Lisence.
As a first project, it would be best to try out the existing game distribution service. The game will be up on steam once the demo is uploaded and the rest of the game is created. 70% of the assets created for the demo are made in a modular manor to be easily fitted with the rest of the game once those levels are made.
The demo will be up here on Indie DB and the games web page.
