I'm doing a bit of work for a friend and she's insisting on paying me for my time as she would have to pay a professional service to do it for her if I wasn't doing it. It's about 15-20 hours work - typing & creating a number of powerpoint presentations. This is something I do in my job anyway so I know the quality is good but I don't know what the going rate would be. Just looking for some feedback what would normally be charged for this type of work. Thx
