You might go for Let us C or ANSI C by Balaguruswamy, but these are not "good" books, they are just average. If you want to read good books, go for "How to Program C" or "C Programming: The Modern Approach" or the god of all books, "ANSI C" by Dennis Ritchie himself. :)

C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language.

well, In unix I heard there are driver programs through which you can control hardware of the computer.. I don't know about windows environment.

Don't charge anything per hour, Look at the market rate, They charge <1000 per complete course, So accordingly, I would recommend any where between 500 and 800 is reasonable for c programming, You can charge a different amount for advanced C concepts.

With a few line of syntax by using pointers, you do much of your task. It is not hard to learn but mastering in pointers not easy :)...
You can see ample use of pointers in data structures and embedded programming. For the newbies, in handling arrays, simple database programming and graphics programming, pointers are not only useful but an inevitable part of the programming language.
