Do I get paid from the buyer, investor, or both?

[Darryl Scipio]

Hello all. I was asked by a buyer of a property under contract to help find an investor to help fund the project. How should I get paid and how much? Should I ask the buyer for a percentage of the loan amount, and if so, how much? Should I ask the investor for a finders fee, and if so how much? Hopeful for some guidance on this matter. I am in New Jersey and I dont have any kind of brokers licence nor do I have a real estate licence of any kind. Thanks.
