You also don't need to "pay" anyone as it's pretty easy to do yourself, jut follow this guide.

I personally don't do anything with macs, but one of the tech guys that work for me loves them so I usually just throw all the mac / ipad setup request his way. I think he's done 2 setups on 8 and hasn't had any problems with either one.
