build a new website with add some function in wordpress

I'm looking for someone to write an image search function for the wordpress plugin Image Store [login to view URL] I know it's been done because someone else said they had. For my wordpress site [login to view URL] to search the various galleries (more to be added). Ability to search for "red" "chevrolet" "1979" etc, and pull up any image with that in the title or description. Unfortunately I don't have a URL for similar work with this plugin. I would want something similar in functionality to google where you can search for a keyword and it pulls up all the relevant pictures. but within the plugin, so they can then be purchased/added to cart. Search feild would be preferably added to the site with a widget, or as a built in part of the cart (to the left of where it says "select/add to favorites/add to cart/ ) project will be complete within 24 hours
