Where to buy aquarium glass

[marcingo]

Hi. Im looking to make a custom aquarium. Does anyone know where to get aquarium glass? Is the tempered glass from Crystal glass ok for an aquarium? It wont be a big one maybe 15-20 gallons so I dont think many things can go wrong. Also does anyone know a good site that shows the whole process on making a tank?

If there is anyone on the board who makes aquariums I would be willing to pay you to either make me one or help me out. Thanks
