How long to rebuild front suspension?

Hello, I'm trying to plan on how many days/hours it will take me to rebuild the front suspension on my Dart. I have all ball joints, all the bumpers, all the bushings, etc., but no torsion bars.

I'm planning on 4 hours two or three weekends a month. Approx how long can I expect this project to take? I am not super experienced mechanic, but know just enough and with the right tools, I think I can do it.

Thanks for any input.
