What corporate job can i fit in?

It depends on what you really like to do, and what your goals are long-term... do you want to be a CEO, do you want flexibility with your hours, do you have a college education or are you willing to obtain one? These are just a couple of the questions...

If you're looking to enter into the corporate world to climb the ladder, so to speak, I would recommend that you look into bookkeeping (Accounts Payable, Accounts Receivables) entry-level positions. Also, you could easily look into Office Management, which may or may not include bookkeeping. An Executive Assistant or Personal Assistant to a CEO would also be a possibility, given what you've said about your background and interests.

If you are seriously looking for something in Corporate America, one of the best (free) resources is to go to an employment placement agency (I don't know what area you're in, but something like Office Team). They will test you on skills such as typing, bookkeeping, and your computer skills. The person who is assigned to you is your job search go-to person, and wants to place you in a well-paying position where your knowledge, skills, and natural abilities can be put to good use. Most work on a placement fee from the hiring company, so they are eager to help you find the right fit for you.
