Generally I think this is unlikely to happen because people who are freelancing often are doing so because their need is liquidity (read: cash, relatively soon) and not equity in a maybe successful venture. Thus they're looking to be paid now for work, not be involved in a longer term personal investment, whether in someone else's company or their own. So by definition, someone freelancing has very different goals than someone with the security and desire to be thinking about startups. For your question, I think you'd need to find someone who very specifically is freelancing but also is looking for a good startup idea, which I think is rare.
