First of all, if you realy only want to make $2K/month, you should be able to do it very easily at 1/2NL. If you can't make that much at 1/2 NL, you have no business being a no limit pro. Your variance should also be lower at 1/2 and you don't need a huge bankroll. I don't really recommend 1/2 for a pro, but it might be an easy way to start if you don't need to make a lot.

2/5 NL is a reasonable place to start as a no limit grider. However, you might think more in terms of starting at 1/2 and working your way to 2/5 and then maybe 5/10. Also, you can play 2/5 but switch sometimes to 1/2 or 5/10 if there is a good game with those blinds.

Also, you may consider playing some online. It might also be good to have something you can make decent money at part time, so you can ease your way into being a poker pro gradually. That's how I did it.

You need to be confident that you can beat certain games. It is better to either gradually become a pro or know that you can make a more than adequate rate for a pro as a hobbyist player before going pro.

Going to Vegas without a lot of money and without confidence that you can beat the games with the intention of making as a pro will put you under a lot of pressure and you may not be successful with this approach.
