why not put it this way.

so many ppl want your pm. 1st, set the minimum investment that you need. what would the capital used for? is that a 'loan' or equity form of partnership? or are you 'franchising' your brand name, doing a gaming chain store to create economy of scale?

then, what kind of person are you looking for? sleeping partner or $ + human capital?

i think you can give out the very brief idea of what you have in mind so that you can filter up ppl to pm you without going anywhere.

at the same time, you might need to have them signing a NDA (non disclosure agreement) to protect your interest.
