Thanks Jully for this topic, im sure there are some freelancer resources are available on the internet but there are only two groups of people looking for them if you are wanting something to be done or you are app/web developer.
To provide an answer for both groups of searchers i would suggest to try this link. No metter what is your need if you are willing to work online you may be the person we need and try submitting your interest by visiting this page freelancer jobs. If you are looking for a freelancer or someone who can do some work for you please send your job right here.
I hope it helps:)
