I live by a couple of stores that carry the Granite Gear tarp, I think only in one size. I also have an Equinox silnylon flat tarp, but a big one- 10' x 12' I could sell you. I pitched it in the yard 3 times, never used as a shelter. Either case I'd send out overnight or 2nd day air, your cost.
PM me if you'd be interested in either! I could get it out tomorrow. Only would work if your in the US, though.
