Looking for a high vacuum 8" conlfat, any suggestions?

Hey guys, I have had a lot of success finding what I need on campus for an experimental setup, but for some reason this piece has been alluding me.

I am trying to source an 8" HV conflat with 5.75" ID. It can have fixed or rotatable holes, be threaded or un-threaded so long as it has at least a 1.5" nipple. Any suggestions?

I have, unfortunately new stuff is expensive.

My goal is to build this new chamber (including mechanical roughing and turbo pumps) for under $500.00. This is one of the final pieces needed to complete this experimental setup, and I am nearly at the end of my budget.
