I need a sharp looking site with a data base.

I need a simple but sharp looking site where people can enter simple information like their address, company name, website, and a description of their company. Also, I need users to be able to find these companies in a data base via zip code, After selecting the companied from their check box, I want users to be able to email those companies. I have sites to show you as references of what I want this site to look like. Feel free to contact me with any questions, best, Ryan
