Basically, what type of metal would you use? I know how do use SolidWorks and make basic stuff. Given that I also know the measurements, and I draft up the stuff on solidworks, would it be advisable to get it made myself? How hard could it be? It would just be a sheet of very thick metal with holes in it right?

I only ask this because I know my college has a metalshop that is closed off to students, however, I know someone who works there who can make these mounts.

This is all hypothetical.
