Driver's side power window not functioning

Hello, the driver's side power window stopped working. I can hear the motor attempting to move the window. I removed the door panel and looking down into the door, the window appears to be within the track along the front edge. But I do see loose cables. I can reach down about three to four inches into the door and feel cables that appear to be hanging loose. There are also a few springs on the cable that look like they are not positioned correctly. Does this sound like the power window regulator assembly needs to be replaced? I have basic skills, and the YouTube videos I have seen make it look doable but not very easy. Do you recommend biting the bullet and having a local mechanic get it done? Thanks very much, Bill
