Ultima,
The computer science field is vast now. Much more dynamic, and that is an understatement, than when I got into back in '73.
The amount of money you will start at depends on where in the US you get your job. Also, to a lesser degree, the technology you are employing.
I can speak for Florida, and an entry level person in the South East (including Atlanta), can expect to start as an employee (not contractor), in the 33K - 40K area. It is down considerably from 2 years ago, btw.
Note that is for coding and systems application development. Administrators may start a little higher, but the glass ceiling is alot lower than with traditional programmers.
Interestingly enough, programming, whether C++, Cobol, or Java, all have about the same range. Very little difference for Entry level individuals.
Hope that helps.
