so nobody has shared any resource from where the OP can get some work... yet everyone is happy to preach that $3 is a very low rate...
as for native writers sh*t, I have seen some horrible stuff from actual american based writers as well as editors. So that "native" thing is nothing but a marketing gimmick anyway.
The content quality, on the other hand, is something that speaks for itself (no pun intended)
If you are writing filler content by just rephrasing every other article out there, then it doesn't worth $5 per 100 words. However, if you are giving me a researched piece with actual actionable advice, then i would be more than happy to pay $4 per 100 words.
For instance, if I would need an article on "How to Up your marketing reports using Google Analytics", i would be interested in seeing actual working guides with pictures and step-by-step tutorials rather than just "4 benefits of Google analytics" type content.
