Need a mobile battery service that covers Downtown, any suggestions?

My 420i has been giving me trouble for the last few days and this morning it just refused to turn over at all. I work near Burj Khalifa and the car is sitting in the office parking garage right now, which is not ideal. I called the dealer and they want me to tow it in and leave it overnight, which is just not going to work with my schedule this week. I've been searching around for someone who can come to the car instead and I found a page mentioning Expert BMW battery installation near Downtown Dubai but I don't want to just book the first thing I find. Does anyone have actual experience with a mobile service in this area? I'm mainly worried about them using the wrong battery or not registering it properly since I've heard BMWs are fussy about that. Any recommendations would really help because I need this sorted in the next day or two.
