I started design helmets for amateur drivers, and gradually build upon that. Actually most of my clients are still amateurs, just now they can afford more expensive and formal equipments. If the Ford factory deal goes through, it will be my break into the real professional level!
Actually if I can do it here, anyone in europe should try their luck as well, given how big the racing scene is, just don't be afraid to present yourself and remember you are a professional, no matter how humble your beginning is.
