Virtuemart Zoom Feature

We have a Joomla extension (module and plugin), that apply a zoom to virtuemart images. At product flypage, the primary image is ok. As the plugin uses regexp to get all virtuemart images that are shown at the page, it's not possible to change primary image by clicking at thumbnails images that are shown at that flypage. So, we are looking at a coder with experience with JQuery and Joomla extensions that: 1. Can help us to change Regexp to get html image and link tags. 2. Make the jQuery script to change thumbnails with the primary image. Our choise will be based on price and developer rating
