Women's handbag designs for ethical handbag startup

We are a fair trade, eco-friendly women's handbag startup company. See our landing page here: www.ethosbags.com. We are looking for a variety of designs to test on potential customers. Our company's mission is to incorporate fair-trade fabrics and eco-friendly materials into moderly-designed, stylish, and functional women's handbags. We want to get away from the "hippie" crowd and target a more main-stream consumer. Someone who is socially-conscious (shops at whole foods, concerned about the environment, etc), but also fashion conscious. So what we're looking for is simple yet stylish, modern, and functional. We also would like each handbag design to have "paneling." This is so we can "accent" our bags with fair-trade fabrics. We want to be able to customize basic bag designs with a variety of different fair-trade and eco-friendly fabrics. I've included examples of what I mean by this. Finally, we are looking for 3 basic designs 1. Small / Clutch style bag. Should be big enough to carry basic essentials, especially a cellphone. 2. Medium Crossbody bag. This bag should be large enough to carry an iPad. 3. Larger Satchel or Tote style. We would like this bag to be big enough to carry a laptop, and also have two carrying options: ether handles and a removable shoulder strap, or a crossbody strap that can transform into a shorter shoulder strap. Please don't hesitate to contact me with any questions or clarifications. Really looking forward to seeing your ideas!
