I'm with Lippy. You can absolutely do it with some good friends in an afternoon. Just plan the entire operation ahead of time and have all the parts, tools, lights etc on hand and laid out. Nothing worse than bringing the whole show to a stop because you are missing something. It's also nice to have a "parts runner" that can make the inevitable speed runs to the local auto parts store while everyone else keeps working.
Run your "team" through the game plan and familiarize them on where everything goes and what to be careful of. Feed them well, but not too much beer until you are finished!
