Hydro test locations in AZ?

I have two SCBA tanks that need hydro (Guppy and 65 cu ft). Joe Brancoto can have it done for $55 including shipping but it will take about 10 days from when he receives it plus the time it takes to ship there and back. Looking to find a place locally that is cheaper and faster :) Any info would be great. 
I'm in Gilbert AZ about 20 mins east of Phoenix.
