Book publication coach

This job is about supporting a publication process and the next steps in this process.
(It's not about proofreading or copy editing)

6-page fanfold learning cards (cheat cheats), which already exist as pdf files ready for printing, are to be laminated and printed.

I am looking for the next step:
a print shop
an ISBN number
legal support
Support with marketing in bookstores or online
marketing strategies
Questions that I have forgotten here.

It's not about proofreading or copy editing
Thank you very much!
