This is a link to how I paint mine.

I think it would be more than possible to exchange the blue for yellow, and use a different wash - Sepia or Mud would work over yellow.

I find this quick and easy, and it allows me to do them in batches. I usually paint 8 orks in one go, and by the time you have finished the final one, the first should be dry for the next step (except washes. Depends on how thick you put them on etc)
