You are opening a can of worms with such question. Just answer this question to yourself, if you had such a system, would you be willing to share it?
I would imagine any system such as moving average crossovers or candlestick patterns or bollinger band moves or whatever can get you a point a day.... IF YOU KNOW HOW TO USE IT CORRECTLY and apply it correctly. The techniques or tools are meaningless, it is all up to the individual. Some people make money simply using moving averages while others get chopped in the whipsaws. So the system is not the indicator, you are the system. If you cannot create yourself as a trader, no one can hand you some random tools to turn you into one.
what are the best timeframes and corresponding moving average crossovers?...I.E..2 hour chart and 50/100 MA etc.
You have probably come to the realization that since you can throw 100 contracts at the ES and it wont blink and since 100 x 1 pt. is $5000 a day, 1 point a day consistently IS THE POT OF GOLD AT THE END OF THE RAINBOW, THE GOOSE THAT LAYS THE GOLDEN EGGS and this should lead you to the conclusion, if you are a reasonable being, that it is not an easy thing to do.
Did you just fall off the turnip truck? ET's officially sanctioned ES intraday trading system doesn't just make a pitiful POINT per day, it makes 3X the daily range! http://www.elitetrader.com/vb/showthread.php?threadid=83604 You will be welcomed with open arms into this esteemed community of traders.
