human hair/beauty products

I'm looking to buy human hair for weaving, braiding, extensions, skin extensions too make wigs, and toupees. I'm also interested in buying a sewing machine for hair. The hair I need is 12-14 inches and 14-16 inches in length for now. The colors I need are; black, dark brown, auburn, and blone. I'd like the hair in wavy, curly, straight, and body wave styles. The hair I prefer is Indian, Asian, Caucasian.
