Data Feed/Server Optimization

I have an extension called Simple Google Shopping. It is supposed to export info from my website into a data feed file but it is exporting the wrong information for the size and color of my products into the data feed. I need to have this issue fixed. Additionally my server is running very slow. I have a Godaddy Virtual Dedicated Server. I need my server optimized so that It is faster. The rating for my server is either an E or a D right now as far as the speed of the server is concerned. I need to get this to at least a B. I agree to pay $100 once both of these issues are fixed.
