There is a huge amount of work and skill in making a board
There really is little money in it
I've made 5 in my life - none very good
By the time I've bought the clark foam blank, fibreglass material, fibreglass resin etc
Then spent 20 hours shaping. glassing and finishing
Fitted fins and leash plugs and supplied fins
There is little money to be made
Add artwork to that bill and a custom board struggles to compete with the chink crap made by computer
Oh also lets not forget the shaping room, tressels, low lights and fume extraction !!
