We have snow......just need Yak now

I need some help folks. We have snow here, so I've sourced the perfect tree topped hill with clear run from the bottom to said trees.

Now all I need:

1) 500+ metres of good rope.
2) Two harnesses (one Person sized, one Yak sized).
3) Bag of nuts (the type that drive Yak's wild).
4) One hungry Yak.

So if you could keep an eye on the small ads and ebay it would be much appreciated.
