I don't have any ideas for you, but you can check Craigslist for free pallets.
Here's the link for "free pallets" in the Tampa Bay Craigslist. I saw a couple of ads in the Tampa/Temple Terrace area. Keep checking because new ads get posted all day, every day. http://tampa.craigslist.org/search/sss?query=free%20pallets&sort=rel#grid
I know there are a lot of horse barns in the Odessa area so you might check with the feed store(s) to see if they have any to give away. I'm sure a lot of their products like bags of horse & cattle feed, dog food etc., are delivered to them on pallets.
Sometimes the big box stores have piles and want to get rid of them. I would ask one of the stores if you could have one or two.
I got some from a local janitorial cleaning supply store. They loaded them up for me too! You just have to ask.
Check with a local carpet or tile company.
Call a moving company.Have seen lots of them on the side of home depot
Please take a couple of photos and let us know what you want to accomplish...a sitting area? A privacy fence? A flower garden?
Thank you for all the suggestions
