Patchwork Fabric

I have sourced a clothing manufacturer in China to produce my own childrens clothing label. However they are having difficulty sourcing the style of fabric that I am after. I am wanting a vintage look which is often found in patch work fabrics. Since I am a small business it would not be viable for me to purchase massive amounts of fabric. I am wanting approximately 50 meters of the one color and need approximately 15 colors in total to begin with.

Hopefully someone can help.
Thanks
Anna
