I built something very similar to this a few years ago, sold it for way less ($3/service), and ultimately decided not to spend money marketing it. Building the product made it super clear that AWS costs were grossly inflated, which they hid with dark UX, and I wanted to help small teams and hobbyists. Today, if you are a small team that doesn't really need more than one large VPS, you should seriously consider Docker Swarm. Not to say that Flightcontrol looks bad. In fact, it looks quite nice. Something like this could save you a lot of money if you would otherwise need full-time devops.
