tanTALK - Tanning Salon Business Owners Community - general airbrush tanning questions

I'm considering adding airbrush tanning to my salon, but gotta admit that I am not really sure where to start. Whenever I Google airbrush tanning I get pointed in about 15 different directions lol. I currently have a Mystic booth in my salon, but would love to add the airbrush option as well. I have a few general questions about airbrush tanning and if anyone can help I would much appreciate it.

- where can I be trained to airbrush and what are some of the best options for learning? classes? instructional video?, etc.

- since I am a male, should I also have one of my female employees trained to airbrush in case some customers would be more comfortable with a female?

- what is the best type of equipment to use? I would be more interested in mobile equipment so that I could also make house calls. looking for good, but affordable equipment.

- for those of you who also have a mystic or versa spa booth in your salons: do you notice if the airbrush tanning is more popular than the booths?

- what is the typical price range to charge for an airbrush?
