Virtuemart and Jooomla upgrade

I have a joomla site running in 1.5. i have started to upgrade virtuemart from version 1 to version 2 but have now broken the site. I need you to: 1. fix the problem with the failed upgrade to virtuemart v2. I am getting following error message: Warning: require_once([login to view URL]) [function.require-once]: failed to open stream: No such file or directory in /home/cosmicco/public_html/components/com_virtuemart/[login to view URL] on line 74 2. upgrade joomla to the new version 2.5. I dont mind which order it is done in. My budget is $50 and i need it doing in one day. Please post links to virtuemart upgrade work you have done in the past. Happy bidding.
