I did my spray tanning course with OMG in Bolton. They have training centres all over England so one should be near you. They are excellent. Very informative and easy to talk to. Ask any silly question and they will give you a good, informative and polite answer. Betsy on here could probably guide you in the right direction. Hope you find what you need.
You have asked this question which was moved to the Biz Geek forum and has received some replies. I dont think you will find anywhere that will cover everything in one go. My advice would be to pick the best individual courses rather than try and do a jack of all trades course.
