Or can anyone speak to their experience hiring from:
Upwork
Gun.io
Fiverr
Coding ninjas
PeoplePerHour
I just launched my startup a few days ago that's exactly this. It's a job board for small software projects. It's also integrated with Stripe, so you can pay freelancers directly through the site.
Please let me know what you think.
I'm currently only beta testing in the US, but eventually I'll open it up.
