Check with your talent pool, that's all of the members in your group including their parents. Does anyone have web experience? If they do here are a couple ideas for your club.
Affilitates - Join an affiliate program and start putting advertising on your team website. Your team gets paid for purchases made through your site. I've got a couple - do you like Thomas Kinkade, Elvis, Flowers, or even gift cards - take a look and feel free to make a purchase. Your club or group can do the same.
Collect email addresses - in additon to the activities or upcoming events of your club - you can include links in the message to "hot products" and maybe make a little money.
PPC's - Google has a program where you can add relevant ads to your site, you get paid each time someone clicks on the ad. I've got them at the bottom of every page, including a "search box" - again - each time someone uses the service, I get a few cents. Your group can do it too! (remember there are rules, for example you can't go through and click a link a few hundred time and think you'll get rich, infact, the opposite will happen - you can get banned from the program - sorry, fraud is bad) When used correctly you can make money 24 hours a day!
