Cash Spinners

i am looking to create a website where users can create a profile, store their credit card info, and authorize my company to charge them for purchases or services. i want these purchases or services to be searchable by anyone visiting the site so they can see what things we offer. the website will serve as a sort of marketplace where? buyers can indicate things that want to buy (like a chair or a facial) and sellers can offer that product to the buyer. if the buyer approves the item, the sale will be processed through my website and the seller will mail the item to the buyer.
