This one guy at my highschool has been making music for a while now but he never has a video to go along with it. I talked to him about it and he said he would be interested in paying me for one. I had no clue what to tell him when it came down to prices. What do you guys normally charge? I know that this could be a pretty big project for me, both shooting and postproduction wise. Remember that this is a very low level musician that only gets around 4,000 views on all his videos, and is just looking to raise that with a better video. Thanks M&A!
