2000 Chevy Impala Driver Door Power Window

Last night when I got home I pushed the button to put my window up. It got almost all the way up but then fell. Never had a problem before. I took the door panel off thinking it just fell of the track but have no idea what I'm looking at. I am trying to find some picture step by step instructions how to replace the motor if that is what needs to be done so I can have someone help me instead of paying an arm and leg at a mechanic. My funding is low so I'm thinking of buying some small c-clamps and putting them on the vertical post the window moves up and down on the hold it up until I have funds to fix it. Please help.
