Build an Autotrader website for Cell Phones

I am trying to create an Autotraderesque website for cell phones. I am looking for someone to design my website similar to [login to view URL], complete with search radii by zip code. This website needs to be very simple and user friendly. What I need: Drop down menus for Make, Model and Carrier Price range from Minimum to Maximum If the phone is new or used Condition rated in 5 stars, 5 being the best condition Speed classification (3G, 4G, LTE) Buyers need to be able to search for phones near them with ease. They can always expand their search if they don't find what they want close to them. Sellers need to be able to post pictures and descriptions of their phones and how to be contacted for the transaction.
