Justin Higgs owns the company, I know of him and have met him a few times when he was with Chilli graphics, it looks like he now at St Leonards on Sea.
I don't know him personally, but one of my mates knows him/has used him a fair bit in the past, he's done stuff on a friends Ferrari and on my mates Lancia's and Mitsubishi Evo. Details on his website. He truly is good at graphics stuff and vinyl.
