We need a vendor imbedded script

Hello fellow scriptors its Mizz Millionz coming at you with a rather complex question. My sister and I are starting a business inwhich we need a vendor script imbedded into a picture board so that when people click on it they pay the package price to post their picture and the money splits towards both her and myself. If you think you are able to do such a script please let me know asap because without it we cant get out business off the ground. You will be paid for your time and effort to help design such a script so please if you feel you are able to create such a script message me here or in the game Blackchocolatebeauty Millions and we will take it from there.
