I'd strongly recommend purchasing a blender rated and warranted for commercial use. Vitamix, Blendtec, Waring, and Hamilton-Beach among others all make commercial blenders. There may be additional brands available locally for you. Contact the listed companies to find the distributors and dealers for your country. If you have a local restaurant supply store you may want to see what they have. A home blender isn't going to put up with the abuse it is going to get in a commercial environment. When it breaks the repair won't be covered by warranty.
