Experience can do better IMHO with poker. There's a lot of ways to practice it for free but those materials that OP is trying to sell, I doubt it that there will be someone who's willing to take it.
As said, there are videos that are published that will teach you some tips on playing poker from basic strategy to the handling strategy. OP, those materials that you took for free, if you mind sharing that let's see if they're all good.
True, experience is much better. There are different ways to practice poker without paying a decent amount of money to instructors. Some sites that you can play poker to practice hard doesn't need materials to start practicing poker. I learned playing poker game in facebook. Facebook have a poker game you can play for free like Texas Hold'Em Poker where I learned playing poker. All you need are internet connection, computer device or a mobile device. Well, It's still a different situation where a pro poker player will teach you about poker personally.
I remember that game and I still play it sometimes when I get bored and doesn't have anything to do. Before with that Texas Hold'Em poker on facebook, chips are harder to acquire but now you can claim millions worth of it freely through their daily bonuses/lottery.
I think it's a good training ground for those who wanted to learn about poker. You just have to invest your time on it practicing as many times as you want and you have nothing to lose if it is about monetary value.
