Hits, Punches, Kicks, boens breaking, etc..
 

Does anyone know of a website that sells any of these type of sound fx by chance?

You should be able to find them for sale simply by googling.

You can find some for FREE, however, by going to www.findsounds.com. They'll have a bunch of that stuff, though the quality is all over the place. You can listen to each one before downloading, however.

Try www.soundsnap.com

For free clips, if you want to buy some then you cant go wrong with getting the hollywood edge body impacts CD
