I want to make $500 a week from BJ

I am completly new to BJ and card counting. I want to average about $500 a week to use as extra spending money because my current job only helps pay the bills. Is card counting effective to make $500 a week? How long can I expect to play in one week to win about $500 a week at the low-bet tables? How much money should I bring to begin the week with? I want to set $500 as a weekly goal and once I reach that point, I leave. I am not too greedy. I know that these questions may seem stupid to the seasoned professionals on this site who make $500 in a matter of seconds, but I am enthusiastic on playing Blackjack. I need a vacation! :)

Thanks!
