Hi guys I work on other peoples cars alot out of my barn not in it (no room) so I'm a backyard mech as known on other forums and I was wondering if there is a place on line to figure even roughly the time that might be involve and or how much to charge? If I buy a labor guide I'll have to make up for that cost and I do this stuff to help people out $$ wise I mean I charge $20 for a brake job for front or rear plus pads, shoes etc. And grease it while I'm there
