Membership Site Owners - How do you pay Affiliates?

Hi

I'm setting up a subscription service (i.e. membership site!) and I had a question.

I was wondering how other Warriors with membership sites recruit, track and pay their affiliates recurring payments?

1. Do you use ClickBank?
2. Do you use PayDotCom?
3. Do you use another Payment Processor?
4. Do you use a self-hosted or "roll your own" solution?

Ideally I'd like to be able to pay affiliates a recurring commission of 50%, and I'd also like the option of a 2-tiered program where affiliates could recruit other affiliates and earn an additional 10% on signups under them.

I'm a programmer and could easily put together a custom solution using PayPal or using a commercial script like AMember, but I really don't want to manage the payments myself if it can be avoided. I like the idea of ClickBank and PayDotCom because of their existing base of qualified affiliates and their reputation in the IM community , but I'm not sure they offer the services I need:

1. I would like the payments to occur automatically.
2. I would like any tax paperwork (for US affiliates and international ones) to be handled by someone else!
3. I would like to have a customer service department for my affiliates to contact if they have issues with their payments

I'n NOT looking for a solution where someone hosts the whole site for me, the system I have built is quite unique and its hosting requirements are very stringent.

I need to get this figured out soon, as I really can't assemble the membership component until I know how the whole payment process works. Any advice would be greatly appreciated.
