  - What YC or any VC would love to see is traction.
  - If you have a simplified version of your idea that's 
  functional, and solicit user feedback, take it from there.
  - Work at it during nights at first.
  - If your growth rate is good, apply to YC.

Note: Startups are still too much work for one founder. So see if a good programmer you've worked with in the past would like to team up with you on this.

Projects that could become startups given funding are not too much work for one founder. IMO your personal interest in the project should propel you to the point where you will need anyone else to help you.
