Please don't tell me that your budget is $700, then once I tell you I'd only require $300, that you then want to see if I can "work down to free".
Please don't tell me that you like my work best and then say "the other eight were building their portfolios, and weren't going to charge; can you do that?"
Please don't tell me "since we're nice, can we get 50% off?"
