Consolidation needed

I have three (3) boxes in Mobile, Alabama, USA that I need to ship to Tarija, BOLIVIA. The boxes are Medium-size from U-Haul, containing clothes, books, and personal effects. In total the 3 boxes weigh 150 lbs, so I'm looking for someone with a larger shipment to let me piggy-back (consolidate) my small shipment. . . . Thomas Perez
