Although eBay may have popularized the idea of bidding on items online, one nonprofit organization is auctioning off business advice and networking time. The Consortium of African American Organizations (CAAO) is hosting a silent online auction, offering one-on-one sessions with more than 80 CEOs, executives and celebrities. 

Users can bid on the specific people they wish to talk to, or opt for the "Buy Now" option to beat the competition of last-minute bids. The proceeds will go toward CAAO's educational and youth programs.

So while you can't put a price on knowledge, personalized business advice from leaders in your industry may offer the insight or partnership that launches your business to lasting sales.--Jessica Chen
