Are you just looking for a 'hairy dude' for your concept, or are we talking about an 8' tall human here?
If you just want a tall human, a simple head-swap on this guy will give you a 7' (as others have stated), or you can just find an ogre figure for your human. I believe the Ogrun from IK would work for you, like the guy shown here (you'll have to scroll about half-way down).
If you like the 'furry look' of this figure, but need something larger, Reaper has a Sasquatch mini that is very cool (looks like Sabertooth from Marvel Comics). Another option would be to look through their Warlord line, which is 35mm IIRC - anything that size will look big compared to standard 25-30mm.
I love this Lion mini BTW, and will have to get it - every single campaign I have ever run had Lionmen in them, and I have high hopes we will find some in PF.
