Quick Fix for Joomla Website

Need quick fix for a Joomla website: 1. The banckend uses Virtuemart for products management. The header menu use side menus, but my client requests use drop down menu. I need a Joomla and Virtuemart Guru to modify current side menu to drop down menu. 2. In Virtuemart, the products images uploaded by client will automatically resize and rescale, since the customer only have certain pixels picture of products , so the image will look very blurry, so need to change the configuration of image resize and rescale to make sure it meets my client's image pixels requirements. My ex-programmer did a very good job, but he is busy for other projects. I need this Joomla and Vituemart Guru to do a quick fix for this project. This have to be done by U.S. Eastern Time 7:30 A.M. 10/19/2010. Thank you!
