I made an invitation for a school event last year and they want to use the same one but change the information/text. I can technically charge by the hour but it probably won’t take me a full hour. How much would someone charge to for this?
I don’t think you can charge so much since you aren’t giving them a new design - maybe $15 - $30 (depending on the school - if you think there’s going to be a lot of back and forth do more money in the first place)
I know many graphic designers who charge minimum an hour.
In this case I would say charge a flat $30-$40
Turning on your computer/ being tied down/ etc for $15 is very low-- even if you do it quickly
