It is possible to start with any bankroll, just play by percentages. Try to keep yourself to about 10% or 15% of your bankroll as an absolute maximum per day. So if you like a lot of action, 8 to 10 bets or more, start with maybe a $15 to $25 range on your plays. If you play fewer games (I play about 2 per day, personally), maybe look at a $30 to $50 range on your plays.
I personally don't do well setting an exact percentage of my bankroll per play, so maybe set milestones. Start at $20 per play, then when your bankroll hits $1200 or some other number, then go up to $25 per play. Then at $1500 go to $30 per play, etc. If you start the season cold, don't be afraid to lower your play amounts, either.
