Hello Jennifer and Mike,
If you are new to e-commerce as you said, then I would recommend promoting your business on-line by social media. When done right Facebook, Twitter and article writing can really boost your traffic. For example with Facebook don't make a regular Facebook page, instead make a fan page. I have NOT tested this myself, because I already get good traffic to my website off my regular page. However, there are many out there that solidly swear by this tactic.
Good luck to you both,
