Is Esoteric Audio in Scottsdale not able to help? They say they carry Graham so I assume they would know how to setup a table. I also see on their website that they have moved.
There is also Audio Video Choices in Phoenix who advertises with a big picture of a Rega 'table on his page.
I don't know anything about these guys, just did a quick google search.
In the end it would be to your best interest to learn how to do this yourself if at all possible.
