When I was looking to have my kegs cut I posted an add on CL in the wanted section looking for someone with a plasma cutter. I had a guy respond that said he could do it for me and just to pay him what I felt was reasonable.
I paid him like 20 bucks to cut 2 kegs, but it also only took like 5 minutes.
As for the holes, I have Kobalt step drill bit that I have used to drill many holes on my brew rig that you can borrow if you have a drill that will work.
Hope that helps some.
