Step 1: Pallet deconstruction time.
Tools you will need:
Back up Hammer
Disassemble the pallets, keeping in mind that many long boards will be needed.
Disregard the base parts of the pallet, they have too many nails in them and are not worth the effort to keep unharmed.
If you lose your patience with removing the pallet wood, simply use the jigsaw and cut the boards at each end, then play around with it until the middle of the board comes unattached.
