starter not working?

[Gr1m]

just got my car back from the autobody shop today...when i picked it up it started very hard...the cranks intervals were very spread out in the begining, but then it eventually started. then i drove it to my moms shop to drop off something, and it started very hard again....so i drove it home and parked it. now the car wont start at all...battery is fine, im assuming its the starter now...and im going to have to get it towed to my mech...this sucks i cant even get to the starter now because my car is so low with the bodykit on it now so i cant even drive it up blocks to be able to tap the brushes on the back of the starter to see if i can get it started...anyway if anyone know what else it could possibly be throw some thoughts out...BTW it doesnt crank at all now, i just tried jumping the car, nothing, then i charged it for like 20 mins, nothing, all of the lights work and the headlights dim when i try to start it but it doesnt crank.
