Hello everyone. I have recently been asked by a client of the firm that I work for if I would be willing to give him CAD lessons. He would like to learn the basics just enough to be able to get simple ideas down of rooms/spaces (he is a real-estate agent so he some design and planning knowledge) mostly for himself. He has a copy of LT, but since his last exposure to CAD was a few years ago in school, it seems unfamiliar to him now. He hopes to do this in 2 or 3, hour and a half sessions. The thing is, I haven't a clue as to what a good rate would be to charge for such services. One site I found had rates of about an hour for this level of knowledge (and up to 125), but that seemed a little high to me. Also, seeing as he is a frequent client with the firm I work for (in addition, I do photography work for him as well for his listings), I don't want to price him too high. Any help is appreciated. Thanks!
