Geotheme Search Engine Customization

Hi Everyone, I am seeking to hire an experienced. fast and reliable freelancer who communicates well in English to write a Plugin/Widget/Code (Which ever is better) for a Wordpress theme we use called Geotheme which can be viewed here: http://www.geotheme.com. We need a developer who KNOWS GEOTHEME! The task is to customize the search bar to make it more like yelp, thus when people start typing in the city, state, etc... it automatically populates that chosen place, and people can search and it will take them to the city that they chose. I most likely will have modifications to be done later down the line on the same site so if you do a good job I will always consider that for future jobs! If you have sample of your previous work that would be great as well.
