Hey aceK, and welcome to the forums.
If your bankroll is $1k, that would be about enough to play at the $5 tables with a $5-$40 spread. You should take at least 10 max bets with you to the casino each session (and that's on the low end - 20 is more ideal), so about $400.
Is your bankroll replenishable? Meaning, say you lose your $1,000... which CAN HAPPEN with the natural variance of the game, are you willing to commit more money to blackjack? If so, then you can theoretically count this money as part of your bankroll too. That means if you're willing to invest another $1k if you lose the first $1k then you have a theoretical bankroll of $2k, and you can base your bets/Risk of Ruin (RoR) from that.
As LW shared, I have 3 articles on this site that I think you could really benefit A LOT from by reading, and re-reading them. They go "from A to Z" in everything you'll need to know to have a winning game. In my experienced opinion, you do not have a wininng game until you can provide the following information before a session:
1) House Edge
2) Bet Spread
3) Risk of Ruin (RoR)
4) Expected Hourly Value (EV)
5) Standard Deviations (to understand the possible swings you could see)
All of this is ASIDE from learning to actually count using Hi/Low, or whatever system of your choice you're most comfortable with. I only push Hi/Low because quite often you might have questions about your count, and questions about other less popular systems will be more difficult to get exact answers on. Also, in just my opinion, I feel it's the best bang for your buck in terms of simplicity and effectiveness. You should evaluate as many systems as you like and whichever one (that's main stream - so no Ace/5 count, etc) seems simplest to you that's the one for you (since you'll make the least amount of costly mistakes with it).
I hope you do re-visit LW first response to this thread on page 1 and take a look through the 3 articles. There's A LOT of useful information in there you should know before diving in to blackjack and the world of card counting =). Good luck, and feel free to post any followup questions or send me a PM.
Playing it correctly means you've already won.
