Happy to report we have more options these days for getting what you need to get it done. I have been talking lately with Zack Jiang of Stalk Bamboo Bikes, an Oakland based bamboo builder. In addition to the amazing work he is doing at Stalk, he has an ebay store to help you get the bike building essentials at a reasonable price. Check out his store here. This is the real deal Zack hand-picks the best tubes and has even visited the hemp farm (yes, you can do in the bay area). To contact them directly please email: email@example.com.
