Mr. Q,
I wrote some FAQs on this question. Go to
http://www.sloperama.com/advice.html and read articles 60, 21, and 54. Also read what Dan wrote on his site, obscure.co.uk.
If you thought the online game providers were the right place to go with your game, you may be right. The big thing, though, will be to network. There are lots of conferences and trade events you can go to in Europe. You'll probably have to invest more money in the effort than that, though, and also go to Asian and American conferences and events. And you should get active in the IGDA as well. If there is no local chapter, form one.
The easy part of your adventure has ended - you made the game. Now the difficult part begins - the business end of it. Buona fortuna.
