shouldn't be too hard to find a worn out trailer with all that stuff rusty and falling apart.
check craigs list, I didn't see anything close in your area but I did see these
http://neworleans.craigslist.org/boa/4355643315.html $400
http://mobile.craigslist.org/boa/4345757368.html $350
http://gulfport.craigslist.org/boa/4261144253.html double axle for $700
hope that helps
