My local cabinet shop has built me some custom tanks and sumps.. i paid $1600 for the last sump one its 8 feet long 25 inches wide,,, 15 tall in the center compartment and 22 tall on both ends 3/4 acrylic flame polished routed edges with black eurobracing and lids .. it matches all my old mrc gear. you might find a local cabinet maker and talk to them.. they have all the right tools to do it.
