I asked similar questions when I did my house. Pulling carpet and lino nails took one full day of sun-rise to well past sun-set worth of work. Punching in the nails took the best part of another day and turned my brain to mush. Filling in all the holes (including the ones left by the carpet and lino nails) seemed to take a lifetime and felt like I had done permanent damage to my finger. As mentioned in other threads, it really is a job that makes you wonder if it is worth doing it yourself compared to how much it costs to get a pro in.
I'm no expert, but know enough to be dangerous...
