I always chuckle on posts like these. If a guy can't even figure out how to do some research on their own on how to accept payments from people in this day and age, you really think someone is going to pay you for anything, let alone picks?
As stated above, if you truly are such a good handicapper and it's all documented you wouldn't need to try and get $20 a week from a handful of people that will amount to nothing, not even enough to make it worth your time.
