2. The best source for recruiting people are face to face interactions and personal recommendations from people you actually know. Outside of this, you're taking a wild stab in the dark.
3. I don't see any solid value proposition that you're providing that any other given person seeking a cofounder hasn't already provided aka low wage + equity. What's new?! Worse, you're not even a US Citizen and the Startup VISA movement hasn't actually happened so in order for you to get your green card status, you may need to come here to work on a sponsorship first. That leaves a lot of iffy rooms for anyone wanting to jump on board.
I'm sure I left out a bunch of other stuff I could be ranting about but if you want to find talented people, get your butt overhere and do it in person.
