I never had great luck selling platinum bucks.

I dunno Rich, I'm not sure we are all gonna line up and tell you our good niches and sponsors.

It might be cheaper just to shove twenties into your pockets. ;-}

Researching and testing sponsors and niches is just part of the biz, guy. It's a hassle and can be a bit expensive, but it's what one does.

Look for paysites that 'feel right', and build a couple of tester sites for them. If you make any sales, repeat. If you don't make any sales, test something else.
