Try Home Depot? I bought 1" pipe from them and they cut and threaded it for me there. I don't know if they have a size limit but worth a shot.
ETA: Yup, Id start there. http://tiphero.com/10-free-services-...he-home-depot/
Im sure Lowes has the same thing if you dont have a Home Depot close.Pipe Cutting and Threading: Home Depot has a fancy tool for these jobs. Don’t worry about doing this yourself.
