I believe hockeynut posted in the networking forum about building stands. Maybe PM him. Not sure where you are located bit I know a guy in toms river for custom cabinetry. He does some amazing work but he's not cheap by any stretch of the imagination.
Another forum I'm on has a great thread for diy stands without using dimensional lumber. Reggie is one heck of a craftsman amd has a pretty sweet tank himself. Heres the link.
