Can laser remove the large cafe au lait spots all over my lower body?

I have large cafe au lait spots covering part of my back calf, inner thighs, and buttocks. I was born with only a small cafe au lait spot on my back calf, but it spread as I got older. I have very long legs (I'm 5'10) so I know removing all of the spots won't be cheap. With that being said, would it be possible to remove these spots, and how much should I be expecting to spend? Can I remove these spots myself if I purchase the laser?
