In the uk it costs about 15 pounds to have them done, a few salons do do them here i believe but i am unsure of the cost. I know i would be a customer, but i like to go to a salon and have to whole kaboodle done together. I think if you could offer waxing, collegen facials, acrylic nails etc and eyelash extentions you would have lots of clients. Permenent make up is getting quite popular also.
