Well, what do you mean it is tarting to take off? Is it starting to make enough money for you to not work on any other things and it can support you month-to-month?
Promotion, ha? A mix of online and offline promotion - link building, silo site structure, Yahoo and Bing PPC (Google became too expensive), press releases, wrap your car with your site's URL and tag line for branding reasons, make broaches and t-shirt and give them away to friends and neighbours, stick stickers on bus stops and posts...
The biggest bang for your buck will be SEO and press releases. But press releases only to the wire services with a hope that a TV station will feature you. Remember NO ONE will feature you because of your site (unless it is ALREADY popular), they will want an unusual/interesting/shocking personal story CONNECTED to your website. They will not feature a site on it's own.
I'd change the domain as well - It has to be immediately recognisable to point to a "wish list" site.
