Average is about $125 for a 1/4 scale airplane. These would be a lot smaller than that.
Spending what some of these guys charge just for decals, I rather keep out of it and go with my own design with paint.
Cutting your own peel-and-stick templates is also an option. Shelf paper laid down on a clean sheet of glass works nice for that.
You can even cut more than one sheet at a time.
Custom Decals = $125 per job.
Shelf Paper = $1.25 per roll.
