The 1st time I bought a freelancing service online was for a manuscript editing. I’ve used several companies and self hosted freelancers.
The 1st time I noticed 5r was for an ebook cover design.
There are many freelancing sites from voice over, to cover design, editing, illustrations, etc. Many of them pay more, way more - - - so why did you choose 5r?
Matter of fact, I know several sites that absorbs chargeback, and you never have to work with anyone against your will.
One editing service has list of buyers and service they want. It falls under 1st come basis, where you as the freelancer choose which ones you want. Unfortunately, your take is 50% and the good jobs are grabbed by others about 1 second after it’s posted.
Again, why 5r?
