Help with joomla and virtuemart

My site is running off of Joomla 1.5 and virtue mart 1.1.2 I need the following done 1-Speed up Joolma- My site is some what slow. Its ran off a Dedicated server. so i need someone who knows joomla to speed it up. 2-Set up a payment process. Users come to my site and they can enter in there own credit card info, paypal name, ect. Payment process must be on my site, not sent to [login to view URL] or any other site. I'm guessing paypal pro will do this? I need someone who speaks English well, and that is quick in response. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows?
