Counter-Strike: Source Internal

Hey guys.
I have experience in external hacking for Counter-Strike: Source, I have made many different programs that function just as they are supposed to, but you are limited externally, or so, in my opinion, so I want to get into internal hacking.

So far, I have done a really basic internal bunny-hop hack, but I don't really get what to do from here. It's a whole different beast going from external to internal, but if anyone can give me a simple push in the right direction, I'm sure I can figure it out!

Any input helps!
Thanks.

Edit :
Sorry guys, I made this post when I was tired, didn't really explain it well.
I just need help understanding how to get information, I can look at sources, but I don't learn well that way.
For example, how do you get information such as LifeState, etc, from an entity.
If anyone is experienced in here and willing to help, I would appreciate it!
