I hate to be a killjoy, but would people with £4k to spend have a Shuker instead of a Fodera or a Ritter. Even before you get to £4k your looking at USA Sadowskys, Fender Custom Shop and a whole raft of others.
I wish the guy all the luck in the world but aiming at such a market is going to be very tough even more so in a recession. Usually it's a case of a luthier creating a cheaper version of an existing model, but this would be a huge leap.
Saying that, he must have done his market research so fingers crossed.
