Ridgefire:
I have three different types of stain that I will use on a set of elk antlers. The type I use depends on the condition of the antlers. On sheds that have been left in the sun for a long time and can actually be weathered I will use an oil based stain applied by hand. On a set that has been harvested and boiled I would probably air brush a stain on and that useally goes allot faster, In either case I charge an hourly rate of 30$ an hour. In your case two to three hours would be a typical charge.
Good Luck
