Homebrew PCBs

Could a tin layer do the same with the better conductivity ?
I could tinplate the board chemically, I guess.Have seen that it is sold ,but have never tried.
the board ,I am about to perhaps make ,is a simple powersupply ,think the man have copied a board from a manual.so the idea of milling was also an idea..but as it is without gerber, think I would have some hours with doing the job :)
I could mill it in a copper sheet on 1 mm and then glue a bit of glassfiber to it...and add PCB maufacturer to my card ....
