Don't know if Payoneer would work for this- the platform could work, but whether or not they would play ball with you on something like this would depend on the product and risk.
You could have the prospect sign up with you via ACH, once their check clears you post the cashola to their Payoneer Debit Card, they buy through your link, and voila, you're prepaid and out of it.
Looks good on paper, anyways ;-)
