I'll second that regarding Brad Stacey, even after much looking around at other installers and bringing in a Customs Cage myself, it was not worth the mess around.
Brad is top quality, knows all the regs, and is efficient.
Also, ask him his opinion on Customs Cages and how much stuffing around and re-adjustment there is to make them fit properly.... You end up spending more in time and labour than starting from scratch and doing it right.
