Best place to order a custom or stock 180 to 240 gallon tank Northern BC

[trilinearmipmap]

I am looking at a 180 to 240 gallon FOWLR. Will need a tank with overflow and probably a metal stand too. I am equidistant by road from both Vancouver and Edmonton (about 1500 km each). If the price for a custom tank is about equal to a non-custom tank, I would prefer custom so I can set up the overflow / holes the way I want. Not sure if it is practical cost-wise to ship a tank that distance, and where is a good place to buy it from. I remember years ago there was some nightmare guy in Alberta, nowadays I don't know who makes good tanks any more. Any suggestions?
