where to get tank drilled + internal overflow

[Alterego]

I looked into building a tank about a year ago and found that Crystal Glass will drill, and install just about anything to your specs. Just make sure you tell them it is for an aquarium, I guess they have an allowable variance for most products and you will need everything to be perfectly square, also make sure they use an aquarium safe caulking.

Go here, order your own bit and do it yourself. I bought one and did it myself cost me $25 incl. shipping to drill 5 holes and an hour and a half of my time.
