Mechanic Job in Salem, Alabama

I just need a mobile mechanic to come to my house and either tell me what's wrong with my trailblazer or help me set it on fire I have a o3 4.2 2wd trailblazer and the motor locked up so I found a motor in Montgomery and had some family pick the motor up for me when they got to this place to pick up motor for me they called me and recommend I find another one so the guy at the place called me before they left and gauranteed me that the motor ran and gave me a 30 guarantee that it would run well took me 6 months to get the motor in there after work when I pulled the blown up motor I pulled transmission with it and when I got other motor I put in same way I took out everything is wired up and put back together except the headlight mounting panel and headlights and bumper and the lights on the dash come on as it should but won't turn over to crank or do shit and I'm stuck I have a cheap diagnostic code reader but no codes or shit comes up on it so help help I'm not working at the moment so money is tight but won't ask anyone to work for less than they are worth get back with me come save the day thanks
