Need to find consultants to teach us how to use Sage 500 purchasing module properly - Located in Irvine, California area.

We recently acquire a UK company that runs Sage 500. We found out that there is not a lot of knowledge in the organization there about the purchasing module and we also have been tasked to learn that function. Therefore we have a need to find a good consultant/partner who can come in and teach us how to use the system properly and help us resolve some of the open issues. We are located in Irvine, a city in Southern California and would prefer someone local if possible.
