It sounds like the engine is turning over but the belts are not moving

So it is basically a shot motor and will need a complete rebuild or a new engine if the crank is shot?

Well that's yet to be determined by testing.... However IF the crankshaft is indeed broken.. Engine block 'line bore' has more than likely been compromised... (Block out of alignment).. It can be checked and corrected if necessary but is fairly expensive to do so! .. Therefore, engine replacement would be the best way to go (IMO).. Good luck with it in any event! .. Let us know what is found.
