Buy Bulk Whey Protein Powder

HelloI am looking to purchase bulk amounts of Whey protein powder (preferrably concentrate 80-82% and flavoured)Doesn't need to be packaged as we have the facilities to do this ourselves, although costs for both options would be beneficial.Looking to start with orders around 100-200kg per month, increasing to more.I would like to know shipping costs to the Uk, nutritional content of the product and the unit and total costs for different amounts.A quick response would be greatly appreciated.Kind regards, David.
