I don't think the math works out well for you. The cost is 12 dollars per essay. If I understand stripe's fees, you will pay 65 cents per transaction. You are paying teachers via paypal, I do not know their fees but it will probably be in the ballpark of 50-60 cents to transfer 10 dollars. So 12 -10 - 0.65 - paypal fees = 0.75 to 0.85 profit per transaction. Not sure how automated everything is, but it seems like you will be doing a bit of work for what amounts to a large pack of gum. Now consider chargebacks. Stripe charges a 15 dollar fee per chargeback. So for each chargeback you lose (15+10+1.25(transaction fees above) = 26.25 or so. I have a feeling you will have a larger than average number of chargebacks due to children borrowing their parent's credit card to get their essay graded. I assume you are paying the teachers as independent contractors? Are you prepared to issue 1099's to all of them at the end of the year? And not to sound too harsh but nothing on this site looks professional at all. It reads like it was written by a Nigerian scammer. EDIT: fixed my math
