Custom sump

Hi all,



I am looking for a custom size sump for my 90 gallon aquarium which I am putting together. The available size in my stand is 46 x 16 x 23 to the top of my door. This leaves me around 8" in order to slide a protein skimmer in the sump with the tank on the stand. I was figuring that I could fit a 35 x 14 x 15 sump in the stand. Would anyone know where I could get a sump or aquarium this size or have one made.



Thanks
