Any tank drillers?

[COWabonga]

I have a 72 bowfront standard tank and would like to put 3 holes into it. What size holes do you guys recommend? 1 hole will be for the drain and the other 2 for returns. All three holes will be along the top back of the tank. I was planning to drill the holes myself, but with my lack of experience, it would be to risky. Does anyone know a place that will drill holes for me. Better if its locally in San Diego. Thanks

Is this glass or acrylic? If it's acrylic it's pretty easy to do yourself. Glass is a different story. Hole size wise, you've gotta match up w/the bulkheads you plan on using ie one inch bulkhead needs a 1.5 inch hole or so--also depends on if you use sched 40 or the heavy duty sched 80 bulkheads.
