Does anyone have a mobile car mechanic they can recommend? My car is dead at home with a battery charging malfunction.

2013 bmw 328i, I got the warning that the battery wasn’t charging and then a few hours later it died. Looking online it looks like it could be the cables or the alternator. Nothing seems out of place so it might be the alternator. I looked online for a mechanic but I wanted one that was linked to a shop. And it’s Sunday so the two I called didn’t pick up. So I’m looking for recommendations. Located near the med center. Thanks.
