Build website for selling data lists

I need to have a website designed and built to sell data lists. This will be similar in concept to sites like infousa, though should not be a clone of that site. Bids should include all required graphics including creating a logo. This will need to be able to run counts based on selects made by the consumer, i.e., they will enter a search area by either zip code or county or state, what type of lead they are looking for and the system will generate and run a query and return the counts. It should allow saving the count criteria and emailing the counts and other pertinent information to the user. The database that this runs with already exists, in mysql and is approximately 200gigs in size (184 Million records).
