A simple webshop/marketplace with a few additional functions

Hello! We would like to build a marketplace/webshop for clothes where the sellers can create accounts, log in, write something about themselves and post products. The products should have pictures, a description and some specifications. The buyers shouldn't have account, just be able to browse sellers and products and add them to a cart. The cart should be integrated with PayPal. There should also be an admin account with transaction history, ability to delete products and sellers. The site should be professionally coded. Detailed design with colors etc. is not a part of the project, but we should be able to run and test the site. If you have any questions, just ask. We want to get in contact with a programmer directly, not an intermediator. It is a serious project, so you must be skilled and able to grasp the main concept of the site. Best regards, JMMFPM
