I know an awesome company in Cali buy the name of Kritter Aquatics. They made 2 custom sumps from me and I'm about to order a custom tank with stand and canopy. Pm me if interested and i will dig up there contact info.
Great company with excellent customer service and quality. When I had my last sump made they sent me many schematics untill I approved and sent me digital pics all through the process and that was only for a 30 gallon sump!
