First, as edw519 mentioned, 30 is still quite young. A friend of mine moved from Japan to the US at 38, taking less than half his former salary, and is still waiting for his green card at 43. He doesn't like his job that much but it keeps him here and the lifestyle is much better for him. I myself am 35 with a wife and two kids. I've been bootstrapping solo for the last two and a half years. Traction takes time (like 2-5 years). You can't just put something online and expect it to grow. You have to physically talk to your potential customers, even if it means doing so repeatedly for very small deals. You're actually quite lucky to be employed while working on your side project. Keep your job (or find another one if it won't screw up your green card process) and figure out a way to keep building on the side (make sure you're covered from an IP perspective). If you really want to make it happen, you're going to need a lot of energy and patience. Also, don't worry about competition. It's the least of your concerns.
