Ask HN: What is the best conference for launching a start-up (minimal budget)?

I'm planning to get some exposure for my innovative & one-of-a-kind e-Learning application (Desktop app). I believe it has a revolutionary value :) I also need to get this done at a minimal budget. I'm a solo-founder & self-funded. After some research I found these options: LAUNCH Conference, Disrupt, TNW (The Next Web), DEMO, SXSW Please feel free to recommend if there's anything else. FYI: I'm an Asian. Thanks in advance.
