Automatic to manual conversion
I am sure you could find one of the smaller shops to take on the job but its going to cost far more than it should as it is mainly just labor (assuming you sourced all the parts). In realty, its basically a bolt in deal (if you are going with factory parts) with the exception of the floor panel. The trick is assembling all of those parts. Of course you could talk to one of the conversion companies for a "kit" to convert it like SST or American Power Train. The kits run around $3000 depending on what you want (5 or 6 speed). So, using a kit as a base, I would think that if you bought one and took the car to a "mechanic" in the end you are going to be into it for $5000+ (depends on how fast they work but you can figure $70/hr and unless they have experience doing this, you are looking at 20-40 hours of labor (yes I know it can be done quicker but a shop isn't going to be in any rush.
