Convert a Joomla module

We need somebody who is able to change a Joomla/Virtuemart module that was written for 2.5 (VM 2) so that it works with Joomla 1.5 and VM 1.1 (make it backwards compatible). The module is not a complex one and it should not require complex framework hacks. It is basically a presentation/layout change. We are aware that an applicant may not be able to give an accurate estimate without actually seeing the module. That is why we will provide a working installation of Joomla 2.5 and VM 2 with the module already installed and working to all serious bidders. Thank you.
