With some extra words in the middle, I bet that could be 30 seconds. (Thank you, newBlazingAngel.)
EDIT: With the new stuff I've added in green, this may well approach 60 seconds long. Unfortunately, my haphazard addition (I had to retype it from memory when my internet failed, but that's irrelevant) makes it so that this now could use some editing to make more sense for a radio ad.
*Though they'll accept donations from anyone, including non-"full members". Full members are obviously the primary donors, though.
**This is just a random number I pounded out on my keyboard. Call at your own risk.
