Breadboards are all well and good for development work, but eventually things that weren't just "a bit of fun" are prone to end up on a PCB if you have the skills. And doing yourself isn't hard.
Nor, it turns out, if you use any one of several software packages to create the necessary "Gerber files" (not hard), is it hard to find someone commercial to make up a PCB for you.
What's hard is deciding which service to use! There are many factors, but even after you narrow the field by your particular requirements, there seem to be lots of competing services out there.
In the absence of a "PCBs etc" sub forum... I will presume to ask here....
Who have you used? Pros? Cons? (As in "reasons to use them"/ "downside". English is so wondrously ambiguous!)
A list of such firms, mostly just names, is available at...http://kicadhowto.wikidot.com/fq1pcbfab2c
(There are also notes on linked pages there on choosing a service, and on making your PCB by hand.)
