Places like Lowes and Home Depot won't carry the pvc sheets that you are looking for. I would look for someone local so that you can reduce the cost by not having to have it shipped. I did a google search for plastics in my state and found a few places. I finally found a great place that had really good pricing that cut it to the sizes I specified and even did it for free. Also they even delivered it right to my home for free because I spent over $100. I got it from regionalsupply.com which does ship anywhere but I am not sure what that would cost.
