There are lots of them.
"Blackjack Attack" spreads are basically there for comparison purposes between games, and are not good spreads. However, if you look at the tables in Chapter 10 (or 12?) there is a column called "Optimal Bet", which gives the mathematically ideal amount that should be bet at each count for each game and rule variation. Your bet amounts should be as close to these amounts as practical.
"Blackjack Attack" by Don Schlesinger is the definitive answer to the question "How much do I bet?" The bet spread advice in "Professional Blackjack" by Stanford Wong is poor and just there to generate comparitive win rates. The betting advice and money management advice in "Professional Blackjack" is very good however. Both books highly recommended if you are using HiLo.
Below are some general "standard" bet spreads.

To avoid variance (and also in 8 deck games) some people don't increase bets until +2. Single deck you try to spread as much as you can without raising eyebrows in high counts.
In theory, each point increase in the HiLo count represents a certain % increase in advantage (your exact advantage can be found in tables in "Professional Blackjack"). You should be betting X% of your bankroll based on each % of advantage you have, and bet zero when you don't have an advantage.
In reality, you will not be able to mechanically rachet your bets up and down with the count for long, or spread a really wide amount, without the casino noticing. Therefore, there is a whole world of cover bets, cover plays, camouflage of your spread, hitting and running, non-optimal spreads, reverse or opposition betting, etc, etc, ....
