10 hours?
First, you need a donor car for pedals, linkage, ect. and different parts for cable and hydraulic clutches.
Second, a lot of cars have a different ECU between manual and auto. and just hope the wiring harness is the same.
Third, a lift to do it all. This is not a up on jack stands/drive way thing.

If you can find the car in a manual, buy it and sell yours. That is the easiest IMHO.
