Mechanic Job in St. Louis, Missouri

I’m looking for a mobile mechanic to service a vehicle at my home very quick. I would like to have someone come out and give the car a good once over as well as look at what I believe is he problem. It is an Olds Alero that needs a serpentine belt. However, there is a catch; the belt itself came off! That doesn’t happen unless there is another problem. That being said the car has also been sitting for almost six months so there could be other minor work that needs to be done! I need a free estimate and hopefully a fix to get he car on the road tonight at a fair price!
