In an effort to come up with as fair of a price for our services as we can, we reference the following web-page: Editorial Freelancers Association; which presents trusted industry-standard rates for work surrounding written content.
Since the page linked above proposes ranges for average prices, our prices are firm on being in the middle of the ranges presented on this site.
This way, we abide by as fair of an industry pricing standard as we can manage. For example, if the service in question is ghostwriting (uncredited writing), the EFA proposes the standard range to be 26-50 cents (USD) / word. We would, in turn, charge the middle price of that range; being $0.38 / word in this case.
