I need proper enlightenment charge my buyer 1. Typing 2. proof read and edit 2. Data Analysis
Charge what your services are worth.
The grammar in your proofreading gig needs some polishing.
There’s no difference between how you charge for each different service. It’s through each order you get.
This is YOUR business, you cannot rely on other freelancers to tell you how to run your ship.
Grab hold of the steering wheel. Bon, voyage!
Take the wheel
My suggesting is to not offer proofreading, (which is all one word, not two words.)
