Help with machining of an adapter

Hello all,

I am after an experience lathe operator (with lathe), in Adelaide that would be able to machine up an adapter for me. I was going to do this myself on my lathe but am not feeling confident to get it right as I only have a small amount of Aluminium billet to work with. Yes I have the Aluminium here. I am wanting an adapter 82mm dia x 80mm long, bored out to around 69mm, to go onto my focuser to lengthen the OTA of my 80mm scope so I don't have to use a 2" extender which I think might be causing too much vignetting in my images. This is only an experiment but if it works thats a bonus. I have the focuser and original adapter to check tolerances. I have made a drawing in Sketchup to show what I want. These drawings are available on request.

If anyone can help please PM.
