Tony,
Your experience does not surprise me. Many moons ago I needed to get some simple drill bushes made,and I got exactly the same response [I posted a post about this some time ago ]. I was told,in as many words to just "Piss off".
Your best bet is to find some small guy locally,who would be able,and willing to oblige. Believe me,there is one out there somewhere.
This is not a difficult job,so any small shop would be well able to do it
Hell,even I could do it !!
