Incentive / Tracking

I'm new to cpa marketing. In fact, I haven't really messed with it... but I have an idea.

Are you allowed to put up cpa offers and allow your users to fill them out to earn X?

And how hard is it to track it?

I know of things like PayBuyPartner, which is an offer management software as far as I can tell (haven't really researched yet, call me a nub or whatever, I like to ask first.. discussion > possibly outdated information). But are those what I should go for?

Basically, and very basically, I've only really just come up with the idea - no other planning - I'm thinking about making a site where users could complete offers/surveys/trials/etc. (nothing tricking them into anything like those dodgy "Enter your # and the PIN we send you ..." offers) and a percentage would go to the charities they selected in their profile.

It'd have an option for a charity of all of the major categories, and any smaller ones that would likely bring more dedicated-to the-cause people, as it seems they would be more likely to do this.

Does that sound feasible? Do you think it's a good idea?

Personally I think it's a good idea because I'm assuming a lot of people are cutting back on their charity donations with all the doom and gloom, and are feeling guilty about that. This would be a way for them to give to charity without spending much time and no money.

But as I said, "assuming," I haven't done a lot of research yet.

Thanks!

p.s. If I shouldn't be looking at cpa offers, sorry, completely and tee-totally the wrong category. It just seems like I would be able to track them some how (what user actually followed through with an offer), and it's exactly what I'd need.
