Why not buy a gun blank that you choose yourself, and have it custom fit to your dimensions? You can do that for about $1000; it take more time, and maybe $600 more dollars, but you will have a piece of wood that you chose, fit to your dimensions.
Check out Old Tree Gun Blanks in Utah. Gordon Smith has a lot of blanks on REALLY good sale right now.

You can get some good wood for $400, then get measured and have a stock fitter make the stock. Wait till hunting season is over and it will likely be ready by next season.
Just another option.
