How much should I charge? -

I m supposed to be helping pretty up for lack of a better word some terrariums for this guy in my class. He keeps asking me how much I want an hour but I have no idea how much to say or how to even figure that. Anyone have any good suggestions? He already has some stuff he s purchased so I would just use what he has and maybe some stuff from my house. He asked me if I wanted like $20 or $25 an hour but I think that s outrageous!! Please help.

you think it s too high? Take the money and run. A fool and his money are soon parted. Then you will have set a precedence for the next sucker to pay the same rate for the same services.
