[Buying] Slime farm (or access to one)

[frobalt]

I could do with some slime in preparation for 1.6 and leads being introduced, so I'm wanting to either:

1. Buy someone's slime farm off them.
2. Buy access to a slime farm
3. Pay someone to build me a slime farm

Put which one you intend to sell me and how much you expect to charge, and I'll get back to you.
