18 MTT for $0.55 would be an option.
The one I would choose would be 20 SnG for 0.50.
This option is slower but more secure as well. A Sng is a tournament that if you are patient you can win it many times and other times enter 2nd or 3rd which already implies ITM.
I would not enter cash tables until I was prepared to play micro-limits and did not have at least between 50 and 80 boxes (that is, $100 to $160).
I would not play more than those limits.
Remember, your bankroll must be 100 bullets Example u$s 100 (100 bullets in MTT of 1.10)
$330 Bankroll (100 bullets in $3.30 MTT)
Bankroll u$s 200 (100 boxes in cash tables of u$s 2)
That is the way to build a bankroll, and logically study, without studying this beautiful game you will not directly build a bankroll)
regards and good luck
