I have a social network project idea that helps people to find their vocations or callings in life.
Best to self capitalize, till you're generating profit.
This will give you far better terms from investors.
If your idea is viable, very easy to bootstrap social network platforms.
For ideas, search Clarity for Meetup.com references + use these postings for audience building.
You can also book calls with people providing business design ideas, which seem to align with your personality + income/timeline requirements.
