Dealing Blackjack?

What do you think as to a profession/job as being a blackjack dealer as a part time job? I am not 21 yet and really need to amass a larger bankroll but the lure of the casino is too great, I work flexible hours in real estate would a job on the inside of a casino being a dealer be of decent pay? would i Learn any valuable information? any comments help.... also how bad is it dealing bj 8 hours a day all week, I have dealt at parties for 6-10 hours but never in a professional casino setting.
