A 24 x 36 granate surface plate is about $125 from Enco. I'm sure the shipping it quite a bit more than for a book. Also, considder just pouring concrete as a surface, you can locate bolts and such with aimple fixtures. There are a few floor leveling epoxies and other extreemly tough compounds as well. As alternatives, considder a marble counter top or old billiar table slates. If you can make a flat surface and lay a piece of glass on it, you could use that to pour your concrete. There are lots of options. But, one thing I could think is that 1/4 inch steel is pretty light in that size. Call around to used tool/machine dealers to see if they have used surface plates for a low price.
