Vince GillVince Gill is known as much for his kindness and generosity as he is for his soothing tenor voice and unbelievable guitar skills. And once again, the multiple Grammy winner is offering his time and talent to a worthwhile cause.

Vince has partnered with social commerce network in an online auction where fans can bid on a 90 minute visit with him. All proceeds will benefit Challenge America, a national initiative to aid the country's returning wounded military. The highest bidder can use the time in person, on the phone, or via Moontoast's Live Video Player, covering any topic the winner chooses, from music to guitars to golf.

This is not Vince's first effort to support Challenge America. Last year, along with wife Amy Grant, he hosted a concert at the Kennedy Center in Washington, D.C., to raise funds for the charity. The show also featured performances by Melinda Doolittle, Allison Krauss, Darius Rucker and Michael McDonald.

Vince's auction, which ends on April 16 at midnight CST, is currently at $1500. Place your bid here.
