Do it yourself. It is rediculously easy; in fact, there really isn't a way to mess it up. Make sure that your scope lenses are covers and shove a foam earplug into the bore. Spray a light coat of tan. Loosly wrap a mesh laundry bag around parts if you want to add a snakeskin texture effect. Go out in your yard and pull some vegetation/ferns/weeds/whatever to use as a stensil. Hold the stensil between the paint can and rifle and add some color (brown/olive drap/black). Keep going until you like the results. If you add too much color or don't like a section, add more Krylon.
If you really want some help with it and feel like driving to Tampa, I can help you out. It only takes about 10 minutes start to finish.
