Store locator plugin for WordPress

A customer leverages WordPress alot and would like a plugin developed that does the following. ? If a WP plugin isn't the best solution for this, please indicate so and why in your proposal. A customer of ours is looking to have a WordPress plugin created that is basically a Store Locator, but it needs to have the ability to show only certain vendors in a single zip code area if need be. The customer wants to have certain vendors that show up based on zip code, and not radius. ? The locator would need to be able to leverage pulling up the locations based upon zip code utilizing their Google Maps API key. They are selling vendor space on a per zip code basis. ? They also want the end user to be able to check boxes on the type of vendor they want to search for from a list, so they can select one, two, all, etc. of the different types of vendors. They insist that the output be clean with the ability to place a header graphic on the output page and the following table items: Logo picture (fixed size) Name Address City, ST Zip Phone Number Webpage Other info The customer also wants the ability to add new vendors to be easy and flexible, meaning through manual entry, or batch uploading new entries via CSV formatted file. The current solutions on the market are basic in nature and don't allow the ability to block other zip codes if need be. ## Deliverables If a WordPress plugin in not the best platform for this, as they want to mass repeat/duplicate the process across different websites, then please give us an idea of alternate suggestions. The output needs to be either in HTML or IFRAME on a WordPress blog. Thanks.
