It's possible, but it definitely depends on your skill level and the amount of hours you can put in.

Playing many tables, you could pretty feasibly run it up to 10K without moving past 25NL if you could put in the time.

If you're asking where to play, you definitely need to play somewhere that has limits low enough for your bankroll. You should be playing 5NL or maybe 10NL (but if you run bad at 10NL, you need to drop back). Those limits are so easy to beat that you can generally get away with a few less buy-ins, but you still don't want to stick around for a downswing.

You need to make it to 25NL, and then I would move to Party. I'm partial to party, however; there might be better sites out there.
