DCist has paired up with the Boost Mobile RockCorps to bring you news of a great volunteer opportunity, and a shot at winning a brand new toy. It’s a marriage of two of our favorite things — good deeds, and free stuff.

What exactly is the Boost Mobile RockCorps, you ask? It’s a volunteer program that’s travelling the country offering free, exclusive, not-for-sale concert tickets in exchange for your time. If you sign up and give four hours of your time next weekend, you’ll receive a free ticket to see either Hawthorn Heights or Ghostface at the 9:30 Club. To see Hawthorn Heights on August 2, you’ll volunteer on July 29 with Volunteer Fairfax. To see Ghostface on July 31, you’ll volunteer on July 30 with the Latin American Youth Center.

To sweeten the deal even further, BMRC is offering one lucky winner a Motorola i855 cell phone, and 5 runners up some pretty sweet stuff too.

So what should you do? First, go sign up to volunteer next weekend. Second, register below for your chance to win a pretty, shiny prize. The contest ends July 27, so get to entering!

UPDATE: There seem to be some technical difficulties with our fancy new contest manager. We’ll do this one the old fashioned way. Send an email to amanda (at) dcist (dot) com with the subject line BMRC Contest by midnight on July 27 to enter.
