My suggestion is, in the future, always ask for more than you think you can get up front. That way if they want to negotiate you can knock a little off and not worry about it. You might want to read a book on negotiations. I suggest "Secrets of power negotiators. One very humble approach might be to say... "I am not a good negotiator and i have already give you my bottom line price." In regards to not coming off like an arrogant jerk... you can't control how people perceive you. If they are saying things and you feel like an arrogant jerk, you're probably being manipulated and might be interested in reading a book about assertiveness like "When I say no, I feel guilty"... which says when people in business relationships criticize you, you should obliquely agree and reassert what you want... "I see how I might be coming off like an arrogant jerk, but I'm still not interested in lowering my rate."
