Cost would vary greatly with the method used. I am not qualified to give an estimate, but if you have good clay on site that can be moved a short distance and packed (1' minimum, 2' better) over the vein of sand, that would be the least expensive and could be figured as a # of yards of material moved so far and then compacted.

More exotic methods like ESS13 (I always get that alphanumeric combo wrong ) or a liner would be notably higher.

P.S. Nice deck. Hot tub and towel rack?
