Okay, let’s tackle this. So Arthur Gerber has skills like Digital Printing, Pre Press, and Graphic Design, which are in demand. He has experience as a Typesetting Supervisor, which suggests he has some level of expertise. Location is City of Cape Town, Western Cape, South Africa, which might affect the rate. Considering his skills and experience, I would estimate his hourly rate to be around $75, which is a reasonable rate for a graphic design professional in South Africa.
