Wordpress Plugin Development - Google Places Finder

I am looking for somebody to create an easy to use Wordpress plugin that will allow the user to find local businesses via Google Maps/Places when searched for via Postcode. Details: I want a plugin developed that will search Google Maps/Places via postcode for specific businesses directly from my website. So. for example, if I had a dentist related website in the UK, and I had a page or post for the city of Manchester. I want to provide a searchbox where the user can type in there Manchester postcode, and hit search. The plugin then searches Google Places/Maps API and displays the closest 10 results of dentists closest to the postcode typed in quickly. I would like to be able to place the Postcode Search box on any page or post via simple line of code, and all the user has to do is type there postcode in to retrieve the 10 closest dentists locally to them. I would like the plugin to display the company name, address, telephone number, and if possible map image of location. On the backend, I want to be able to change the business type the plugin searches for, so it can be used on any Wordpress site, related to different business types. I want all rights to the plugin once created, as this may be packaged and sold. Budget $100
