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.
