Question for people working in an office/for a company in some way

As a data point for OP to consider, I charge 10NT per word for proofreading.

Figuring 30NTD to 1USD, that’s about pretty standard. I know a few proofreaders who charge 50 cents per word or maybe a little more on the high end. For the cost of living in Taiwan, 10NT per word comes out pretty comfortable if you have consistent work.
