Renewing Vows In 2009...Need Help

My husband and I are planning to renew our vows on Aug 8, 2009 (our 4th anniversary). We got married Aug. 8,2005 just one month before he was due to deploy to Iraq. He ended up getting held back a couple of months due to the upcoming birth of our son. My husband has since gotten out of the Army and we moved from base in KY/TN (where I am from) to California. We had a court house ceremony with only 2 friends present. Now we want to do it right. We have picked a location, Wedding Rock, Patrick`s Point, CA. And we know we want to reserve a group campsite and BBQ after the ceremony. But that`s all we know!! With an on location wedding and a VERY SMALL budget we want it to be amazing, casual, and fun. Can anyone offer any advice please?
