Pricing help needed :)

Hi! I’m trying to figure out the best way to price a project like this. Someone sent over about 150 google doc files with text. They want me to just place all these files into a nice format but the template is already done and it’s all the same look. Each one would take me about 5-10 min. How you go about charging for this kind of project? Per file? By the hour?

I would say, don’t undervalue what you’re doing- remember, they’re hiring you because they can’t/don’t want to do it themselves. You’re saving them loads of time.
Why don’t you multiply how much you want to make per hour by how long you predict this will take you. Usually that works.
