this is going to take yonks...... I remember doing a saxo vts rocker cover took 4 days with one of these kits.
 
you can pay someone to do it, I've seen prices range from £30-50 etc, they use proper machines designed for doing this, and the end result is always far superior then scrubbing away by hand.
 
Right brought a polishing kit from halfords and thought id give it a go!

I started on the inlet manifold and well happy with the results and just took me under an hour, I half polished the rocker cover and half painted and think it has tidied it up well.

Heres some pics:
