oscommerce database optimization

Hi, My site [login to view URL] is an oscommerce ecommerce site that sells t shirts and other types of apparel. My site is very slow when navigating around. I think this might have to do with the way the products and database is setup. There was a lot of customization done over the last couple years and my site is very, very slow. To give you an idea, we have have about 700 t shirt designs where every design comes in 7 different styles, with over 20 colors each. I need my site to work much faster. Only bid if you have specific experience in doing this. I will need to see that you have completed similar projects before considering to hire you. You will need to benchmark the speeds of navigating around before the project and after and then show the increase of speed. reply with mrteees in your PM. Only serious bidders apply. If this project goes well, I will have several others for this site and my other sites after this one. Thank you, Mike
