I do hair bows too! I started selling them last summer at the Farmers Market in town. Super cheap, but more than enough to cover both the time cost and the material cost. I bought most of my ribbon off ebay in huge lots for huge discounts, and I bought my pin parts on ebay as well. I find if I'm looking for a lot of something that's the best place to go. While I couldn't control all of the colors/patterns that came with the lot, I got a good variety and was able to purchase only small amounts of more expensive speciality ribbons to make my hair bows go from "cute" to "Woah!"

I'm not seeing any pictures you posted... but I would love to. I'll try to find some of my own as well and post them up. I've got 2 little girls, so we use a lot of hairbows!
