Custom Aquaria -- Advice and References requested

[Matt]

In downtown Edmonton, a friend is considering a custom reef aquarium, builtin to an existing cabinet in his office. Dimensions of the desired aquarium are roughly 56"L x 28"H x 18"W. My thumbnail calculations say this is ~100+gallons. He'll also need a frame retrofitted into the cabinets to support the weight, and a sump fitted into the cabinets below. The initial discussions also call for an RO/DI unit and a water change mixing tank in an adjacent cabinet (hidden). The cabinetry is already plumbed with water and power (a wet bar, essentially).

Anyone want to recommend where to go for the pieces of this? Vendors may feel welcome to reply, but I'm really looking for references. Vancouver isn't too far to go for the parts, and he's willing to do some of the general contracting himself, so it doesn't have to be an all-in-one service.

All advice and all references are welcome!

Regards,
Matthew
