build me a website

The project is selling a product with orders, and the order transfer to the vendor on an mobile application, choosing the vendors according the product type and feature , then the vendor reply with price and photo. If the client don’t choose the offer the website transfer the offer on the search, as when some one order it again can find it without sending an order to the vendor again . Note : i need an ios and android app and a website the project is more than simple i want it to work on logic side . We don’t need a perfect design just a fullyfunction working system to be tested in the market . Put in consideration we are student and our budget is not high at all .
