How much would you charge to airbrush on a p-40 warhawk scheme?

If you're not familiar with it its the scheme with the sharks teeth and eye, thats all I want, nothing else, just the mouth and eye on the right and left side. The fairings are in good shape, I just want that airbrushed on. I thought About painting it, but I decided against it because i'd be too much off a hassle taping off everything that needs to be detailed and I think airbrushing would be the best way to go if its feasible enough money wise.
