You have to start creating customer funnels. This could include writing a blog for your target market, doing a speaking tour for shoppers and getting them to sign up, just a few examples. Make sure to get creative with it. Last but not least, I'd refrain from using the word "cool" when describing your product. You should think about how Ultimate Gift Lists adds value and is more unique than your competitors or how people shop now. If you're to do this through your product and vision, that's when people buy.
Business people are obviously important in startups but tend to be dispensable. Find another co-founder, there is a surplus of business types. If you can sell your idea and vision to someone while being technical you'll have no trouble finding another partner. Good Luck.
