going pro, or no?

I guess my question is how much cash should I have backing me before I take the plunge. I currently have about 18k but would feel much more comfortable if I had about 100k. My monthly nut is about $3200.00. I figure I win about 80% of the time I play with an average of about $400.00 I think If I had more time to invest playing without the day to day worries of my job, I would not only get better, but earn more. Should I wait until I feel more comfortable with my financial postion, or take advantage of the extreme growth currently in the poker world?
