It would cost a decent amount depending on how much of the work you can do your self considering you put labor in there as a price.
By what i can see it looks as if the whole jeep has been armor coated like mine, I was lucky i had a friend that is a professional painter and all i did is prep it and he re prep and then sprayed it for cost of materials.
your looking at alot
Warn winch 600
Kc lights x4 probly around 500
custom tube doors 289 dollars quadratec
Probly bushwacker fender flares probly around 250-400
looks like it has rock sliders 200-400
front bumper 300-500
Im sure rear bumper 200-400
complete paint job done right 1200
tires, probly another 1000
if its lifted probly another 500-1000
rims probly 800-1500
Now that is just estimate, you could probly spend alot more or alot less depending on where you are looking for the items and what kind of deals you can get for yourself.
