You've received good advice from DodgeMan, Orezok and Crashz. Here's a rehash from another Civil Engineer. Consider what you are going to spend on the structure vs the cost of fixing your site before gambling on the uncompacted fill.
It may not be all that expensive to strip it off including 6" or so of the supposedly undisturbed areas and have a legit excavation contractor recompact it in lifts. This is starting out as a hay barn but you know how it goes - at some point you may want it to be something more.
Yes you can auger down to undisturbed soil if you can find an auger long enough and big enough to set whatever size blocks you need as bases for the posts. But, the slab is another matter entirely. The cost of a heavily reinforced slab to maybe make up for the uncompacted fill will make stripping and recompacting look like a bargain.
