If you have most of your debt paid down, then I'd bank that extra cash for the moment, and start looking around for another niche to build or buy a site for. I have a lot of different sites. Some make money, some don't (yet) I've shut down sites that I just couldn't make perform. Many of my sites are seasonal event-driven sites, so I've tried to arrange it so that I have most of the year covered. My biggest issue is lack of time to devote to all of them, so the best earners get most of the attention. If I were you, I'd just start with one. But take your time, look around, and see if you can find a niche that fits. Meanwhile, you're saving the money, so if you need to hire copywriters or designers to help you get going, you'll be ready.
