You'll need a club charter, a board of directors or officers, and in many areas, a city or county license. Check with your city or county clerk for more information on these requirements. You should also have a membership contract, the original for your files and a duplicate for the member. In most cases you can write your own, using any organization membership contract as a guide, or you can have your attorney draw one up for you. You'll also need a membership booklet, or at least an addenda sheet to your contract, explaining the rules and bylaws of your club.
Some clubs even give membership certificates suitable for framing.
You can pick these up at any large stationery house or commercial print shop. It must be as impressive as you can make it. It must be legal, while serving your needs almost exclusively. Basically, you should have at least 100 members before you begin concentrating on arranging trades. As stated earlier in this report, the easiest way to recruit new members is to run an ad in your newspapers, and perhaps even on your local radio stations as well.
