Mechanic Job in Avenal, California

I'm in need of a good mechanic i have an 08 Cadillac CTS that has needs the rod bearings changed, i had someone i thought knew what he was doing. He took them out but could'nt figure out how to put them back on, so now it has been sitting in my driveway for a few weeks now and i need my car fixed as soon as possible. I was told the original problem was the oil pump so i bought one so i might as well replace that to now that i have the oil pan dropped. I live in a rural town hopefully someone can come out here and help me with my problem.
