Have you looked at water transfer printing AKA hydro dipping?
I've just sent off a few interior parts of mine for dipping locally. Haven't got them back yet but from seeing results in other peoples cars I know it's going to look amazing. Much cheaper to do, hard wearing and you can have any design/pattern & colours you like.
Take a look at this site: http://www.aquagraphix.co.uk/
