Ive sold companies and taken them public -- the channels for sales are the following:
Lawyers -- in my market there are a couple of big law firms -- each has a deal guy for this stuff -- get to know him. This is what linked in is for -- not so much slashdot
ip lawyers -- unless there is a patent here -- probably not.
vc's -- this is really where you are -- you have a product - you proved it can sell ( the games you make, not the framework ) - and now you want to raise money for some business talent to help monetize it. be prepared to part with most of your company, lose control and have an outsider as ceo. Its not that bad -- and is really the stage you are at.
not all of your team will want to do that -- too bad -- they can leave, but they will leave some ownership behind as well.
if your company turns out to be sale worthy -- they as well as your new ceo will have the contacts to make it happen -- mostly that happens when you dont need it to.
now for the next question -- how do you get vcs to pay attention to you -- thats still challenging -- but at least its the right problem. Good Luck
