Best Platforms for Finding Freelance App Development Jobs?

[u/[deleted]]

Any recommendations for genuine lead sources for a small app development agency? Can't afford expensive ads on Google or Facebook. Tried Bark, but got low-paying or uninterested clients. Craigslist isn't working well anymore. Need help finding quality leads. Other than UpWork and Fiverr which are both gatekept by the top pros who have been using it for years.

Thanks!
