I'm looking to setup a website to sell digital products like selly.gg (here are some other alternatives shoppy.gg )

this is my purpose :

Seller list a item for 5$ => Then buyer pay through BTC for a address

 and my cutoff is 3% for each successful payment from a buyer => then BTC need to release from received wallet -> 97% for sellers address  and 3% for my address.

please let me know how can i get this done.

Thank you.
