From your question, I might assume you have not taken your cc course yet...They would cover a host of issues like this - for instance, there is an agreed-upon list of newspapers in your area,that meet the criteria of the permitting process and your trainer would be able to guide you on that question. I think most applicants have taken the course first before doing anything else, as a matter of good strategy, to make sure the timing of all the application steps goes right. You will find sections on this website about the steps necessary to get a permit.
