Hi Louise - I'm in the Northwest and did my spray tan training with Wow Factor and it was fantastic. The trainer was absolutely fabulous and it turned out I was the only one doing the training that day so I had her all to myself.
I'm a bit confused but it looks like WOW Factor might have changed their name to Beautytrix but if you search WOW Factor + beauty in google you'll end up at the right website.
I'm not so sure you're going to get too many responses to your question in the the 'Consumer Queries' forum. Maybe check out the 'Skin Geek' forum for threads about training, I'm sure you'll find plenty there
