How to create a money lending app linked to a paypal account

I am looking to design a app where I can lend money to my local community. I would like to pay money from my paypal account into their mobile money “wallet”. I am a non profit business and I will only charge 2% of what they borrow. Are there any videos to help guide me online as I cannot find any.
Any help will be greatly appreciated.
