Have you done your training yet? If not you'll need to get that sorted first, which will mean deciding on a brand, at least to start with. Do you have a favourite? What I did was book myself in for a spray tan with a few different salons offering different brands to see which I preferred. I wouldn't buy your kit until after you've done the training as they may well offer you a good deal. However, in my honest opinion I wouldn't pay inflated prices for a pop up spray tent. (I got mine on EBay - Spraytanpro for about £35 and it's been brilliant). You can get trial sizes of spray tan lotion and it's definitely worth experimenting as it's down to personal preference. Look at previous threads on here and you will find loads of tips and advice. I hope that helps to start with.
