Congratulations – and good luck!
I recommend consulting your local printshop and taking a class or two if you have the resources. But once you do decide to take it on, I recommend you work with Boxcar Press.
I used them to print our printing plates. Their professionalism and quality of product are pretty fantastic.
The prices are also quite fair (you know how some Etsy shops will charge $60 or more for a custom plate for an invitation or business card? Boxcar’s minimum is $30, and they charge by the square inch).
They have a highly comprehensive Q&A section and really know the business.
