I considered doing spray tanning a while back but tbh I would be hard pushed to find a) the time to train for it or b) the time to fit even more clients in. So I didn't do it in the end. The thing people ask most if I can do is eyebrow shaping.
I am mobile and offer both waxing and spray tanning in addition to my nail services (enhancements, manis and pedis).
I have found that I get allot more business from tanning - which is great as tanning is quicker, easier and more enjoyable than waxing!
