Where can I find a Whole Seller for Yarn, Wool or other such products?

A wholesaler? You can't buy wholesale unless you are a registered business, and you would have to supply a letter from your accountant proving this. If you mean buying in bulk or large quantities, then I'd advise you to join the international knitting and crochet forum Ravelry. You can ask questions there relevant to whatever country you're in, and I'm sure someone will know where to get good priced yarn.
