Do I Have Enough Info To Go Pro

[Good Idea]

Last December 17th I decided to take poker seriously and keep records of my results. I started with $200.00 and played 2/4 limit as well as MTTs. Here is the situation as of July 1st.
Hours played 460.66
Win rate $13.99 per hour per table (usually 2 tables)
MTTs - 154 played with net wins of $1,159.46.

The plan is to get a new computer w/ 4 monitors. I believe I could play 4 tables if I could see them all. I'm estimating that my win rate would drop to $10.00 per hour per table (Just to be safe) which would still be $40.00 per hour. I would also get pokertracker.
I've pretty much stopped playing tourneys because there is more profit in ring games.
The question is, do I have enough information to make the leap to pro? I've heard people say you need 100,000 hands but with the amount I play that would be two and a half years from now.
By the way, I'm planning to buy the new computer and play 4 tables for a couple of months just to make sure I can handle it without stressing out before I quit my job.
I'll also need time to work on a sales pitch for my wife.

Any thoughts?
Thanks,
G.I.
