TNT basketball analyst Charles Barkley is launching a contest starting today that will reward $25,000 to the person who submits the best business idea that needs some financial support. Submission to “Earn Chuck’s Bucks” at www.charlesbarkley.com will be accepted through July 18. Barkley will then narrow the entries to three finalists, and voters can then go online and “help” Barkley pick the ultimate winner. The winner will be announced in September. I’ve already submitted the winning proposal — “The Jump to Conclusions Mat” — so better luck next time.
