Hi there!
I trained with Gateway Workshop and they have venues up and down the country well worth a check, I didn't get on with Crazy Angel or Fakebake, I love Norvell it's organic and clients have said it doesn't feel sticky like the others!
Once you have passed, email as many companies as you can asking for free samples, you should get enough for 1 spray tan, try it out on the same client as get them to test longevity, colour, smell etc!
I got free samples from,
St Tropez
Norvell
Fakebake
Crazy Angel
Flirties (you just pay P&P)
Beaubronze
Kissedbymii
Good luck!! X
