Virtuemart - Joomla Template - Mouseover Image

We need to develop some type of module or plug-in for Joomla-VirtueMart. The estimated time to perform the project is 2 hours, but we can wait for up to 24 hours, once the project has started. Instructions: The web site in JOOMLA/VIRTUEMART is ready, we do not want to modify the design, we just want to insert some functionality to the images. Brief description: VirtueMart allows you to place an image to the product and several images on the part of the detail. [login to view URL] What we are requesting is that the product image may be changed by placing the mouse over the image. Attached please find sample link: [login to view URL] COMMENTS We are aware that this job is very easy to do, but we are new in VIRTUEMART usage. We are willing to pay from $25.00 up to $35.00 per module or plug-in. We are not interested in having the rights, so you can sell that module to whoever you want!
