521903 PHP and Jquery navigation project

Hi, I am launching an online toy store using opencart 1.5.2. I have basic knowledge of CSS/HTML/PHP and have worked my way through adapting the design and layout. I have seen some features on other sites (possibly using other open source packages) that I like and that I don't think would take much work. There is a possibility for ongoing work as the site grows and adapts and new features become necessary. The first mod I need created is a search mod that dynamically updates as you click on it. It appears to be a bog standard feature on most sites but isn't available with opencart. An example of this in action is on the left on this page - [login to view URL] I don't believe this will take much work and as a project it is almost within my grasp as a rookie programmer so I know roughly how much time it will take. If you already have a mod like this working I would like to take a look at it before we agree anything. Of course I want the design to be easily updatable by editing css. I have attached a copy of a search module that I have purchased so that you can see which files within opencart will need to be updated to create a functioning module (needs to appear within modules in the opencart admin panel). I would prefer if you are contactable by instant messenger as it makes changes easier. If you are familiar with opencart then feel free to bid, if you aren't then I would appreciate if you could download the latest version and set it up on localhost or your own hosting just so you can appreciate what needs to be done. Thanks Evan PS. This is a repost as I found no suitable programmers, please don't apply if you will not be doing 100% of the work yourself, I want a programmer I can communicate with, not a company.
