Dan,
I originally set up my Florida nonprofit in 2001. Because that was years ago, I don't remember exactly how much it cost to set it up. Seems like it was under $100 though.
In Florida the nonprofits are set/up and registered through the Florida Department of State, Division of Corporations. Alabama probably has something similar in place. The Florida website is
http://www.sunbiz.org. My nonprofit, Delta Star Radio of Florida, is listed there. This has to be renewed every year and costs just over $61 annually. My paper trail is public record (as is everyone else with a corporation.) We have four members of the board.
As far as registering your nonprofit name, it just has to be one not already claimed and in use.
When I first organized mine in April 2001, the state found one item that needed to be amended, which I did, and refiled the form. Everything start to finish took maybe three weeks before our charter was granted. It took one phone call to the state office, and a few hours doing paperwork. I have kept the organization intact all this time.
I did not try for an LPFM during the first window because at that time I had a full time position as an operations manager/sales/on air personality for a local standalone AM station. Spent 13 years at that station and thought things were secure, but retired in 2004 when I saw a Titanic situation developing with the owner, and simultaneously had a family tragedy to deal with. It was hard to leave knowing I might never be able to find another terrestrial radio job in the market. And I have not been able to.
The family situation led to having two step-grandsons to basically raise for four years while their mother recovered, developed a career and basically started all over again. All are doing really well now, but radio seemed way less important than stepping up to the plate for two toddlers deserted by their father. So I felt God was telling me to re-prioritize things in life. I have no regrets for making that decision, but financially my wife and I had to sacrifice and we took a major financial hit.
I'm telling you this because you will have days you feel confident. Other days you will want to give it all up and forget it.
At this point I have an application nearly complete except for the engineering page. I hired someone else to handle it and many here would know the company. There is Plan A, Plan B, and if it all falls apart, a non-radio-related plan that relegates radio to just a hobby.
I was reluctant to share all of this here, but most folks in my market know it all already. My stiry has been in the local paper as the "legally blind Tallahassee broadcaster that wants to bring local radio back..." etc. Push with all your might but keep your other options open.
You have a good heart RDP. I hope you find encouragement in some of this.
