Can anyone recommend good freelancing communities?

Hey peeps. I'm looking around for communities specifically dedicated to freelance work - whether for software development or otherwise.

Specifically I'm trying to find some more places to get feedback on the fixed-price model I'm testing for ☒. The Roast post gave me some good feedback on the page contents, so now I'm trying to find more examples of others doing this or other signals of validation.

Of course, the best way is to full launch it and go from there, but I'd just like a bit more data before that :) 

Hey Nik - I've got a community of 650+ founders building across a lot of industries - might be quite helpful for some feedback and launch advice. - here's the link (forgot to post it earlier haha)
