Depends on the car,,,,,did you buy the motor or the motor and regulator,,,,,which is the cable mechanism that moves the the window up and down,,,,I've replaced a few and they can be a pain,,,as far as cost,,,,,at least 2 hours of labor,,,,

Not know what car you have I will guess at about 2 hour of labor.. Most shops are about 75 to 85 dollars an hour around here... My shop is about 85 an hour and that would put you at about 160 and No waranty if you use your motor... Only a guarantee on the labor...
