UV exposure is the closest method to what you used. The only difference
is the way in which you generate the artwork. For me, a single tracing
paper print works just fine (clear coating it actually does seem to
help, I had an excellent exposure a few days ago, no touch up needed at
all, not even to the artwork, no shorts at all, no breaks at all, board
size about 5x4cm) with dry film, UV Leds, 55sec exposure, sodium
carbonate 30g/L cold to develop.
I do down to about 12/12, could do less if really desperate, but not
worth the bother.
As for advertisements, they are not necessary here, we have Google and
there are established cheap pcb prototype houses (iTead, Seeed Studio,
OSHPark, Smart-Prototyping, PCB Zone.. that's just off the top of my
head) when you want to move to a small "run" of production quality
boards. For which you should have no trouble exporting the gerbers from
any half decent PCB design software, of which there is an abundance of
free and paid ones.
