Best course of action

I won 1.50 in a freeroll and have since parlayed that into 5.85 in a combo of tournaments and .2/.4 limit games.
I'm NOT willing to make a deposit at this site. I want to see how big I can make this bankroll without ever investing in it.
That said, the least expensive a tournament is is $1.10, a hefty sum of my bankroll. .2/.4 limit is fine, but not exactly thrilling. This would make it take awhile to get the bankroll up to where I can play higher stakes. The smallest no limit is $25.
What's the best course of action (tables, tournaments, etc) in order for me to turn this into a hefty bankroll? (without depositing)
