Make no mistake, the only reason you have been encouraged to do this "project" is because your "customer" is looking for a bargain. To you it may be fun but they are the ones laughing all the way to the bank.

Thanks for that revelation. Wow. I didn't realize he was intending to save money. That changes everything.

I get to do some fun and interesting work, learn how to do something I haven't done before, and get paid more than most of my friends. He saves a substantial amount of money, and may have to deal with inconvenience of me being inexperienced, and it's possible he may have to call in the pro's.

Sounds fair to me, but I bet you would prefer it to be yourself laughing all the way to the bank, which is why you are being hostile. Not a big fan of capitalism, are you?
