Database Optimization - CRELoaded Shopping Cart

Looking for someone to help optimize our database queries for our client websites which are very mysql intensive. Database is based off of CRELoaded with modifications to incorporate use of a classification system to each product. Extremely high load times for all clients on the server because of this. Need a developer/programmer to be available Mon-Fri 8am to 3pm PST. Work and discussion can be done via Skype at vividracing. International programmers ok. If work is good will add you to the team for weekly tasks. Dan
