I just emailed Jeff, he is building skimmers this week, so if you are interested, I would email him ASAP, I think he only builds them intermittently, and only does the big ones as he needs them......no backstock.
Mark Parks and SouthWest Seas is doing my sumps as well as the tanks. A guy named Dominic has been building his stuff for 20 years. Dom has a great reputation here in the Valley, though you can't do direct to him.
Titan Aquatics (also local, though one of the largest builders in the country now) builds some pretty slick sumps. If you want something really cool, talk to Brian Harnish (owner) there, they are pretty innovative, I toured their facility. They also own a Skimmer company (drawing a blank on the company) that make some really nice high end skimmers.
I went with SW Seas, because on a project like this, I wanted a hands on expert to help me.....Mark Parks is fantastic
