adrianp, I don't know what country you're from, but on the unlikely chance you're in the UK, you can register your ideas using
this site.
At the moment I too am looking into getting a game project off the ground. I'm trying to look on the bright side. If Jonathan Boakes can achieve the success he has had with 3 adventures pretty much on his own, there's plenty of others to follow in his footsteps.
Good luck adrianp.
