How do I buy supplies at wholesale prices?

I want to buy fabrics at wholesale prices, then use the materials to make stuff and sell it. I thought I could do that with a resale license, but it looks like I can only resell the materials according to the FAQ on the application for California. How do small businesses get a good deal on materials?

Unless you’re buying from jobbers, wholesale fabric minimums are typically quite high, usually at least 1000 yards per fabric and colorway.

You also need special manufacturing licenses in California: http://www.fashion-incubator.com/archive/apparel_manufacturing_in_california/ http://www.fashion-incubator.com/archive/studying_for_the_california_garment_exam/ http://www.fashion-incubator.com/archive/sewing_contractors_fabric_resources_in_california/
