Transfers I would look at H Lloyd Cycles, there are also some good traders on eBay.
Repainting depends on what you want, I have Argos Racing local to me, they can do a one colour respray or they can reproduce some of Dave more exotic designs, the the prices soon rise to eye watering levels as things get complicated.
I don't have manufacturing dates in the register, but if you are the original owner then there is really nothing I have that you don't already know, that said a frame made in early 1989 will have been one of the very first Dave made himself.
