The building of the sump is pretty straight forward as you can go with acrylic or just modify a glass tank with baffles. What I would worry about is drilling out your tank. Corner tanks have a very large footprint and need to be supported accordingly. Any drilling of the bottom might compromise the integrity of the glass and weaken it. I would definately find an "expert" to do the drilling and get his opinion. Might save you some grief in the long run.
