Fast Mustang battery replacement in Business Bay, need someone who knows these cars

I'm sitting in my office parking in Business Bay with a dead Mustang and a meeting that starts in 45 minutes, so I'm pretty much in emergency mode right now. The car has been showing signs of battery fatigue for a week, slow cranks and dim lights, but I kept putting it off and now it's finally given up on me. I've called a few mobile services but I'm really hesitant to just pick the first one that answers because these Mustangs have specific battery requirements and I've heard horror stories about people putting in the wrong battery and messing up the entire electrical system. What I need is a fast Mustang battery replacement in Business Bay from someone who actually carries the right AGM battery for the GT and knows about the memory saver and reset procedures so I don't end up with warning lights all over the dash. Has anyone here used a mobile fitter in this area that they'd actually trust with their performance car? I'm pretty stressed about this because I can't afford to be stuck here all day and I really don't want to damage my car with a botched installation. Any recommendations would be a lifesaver right now.
