I've had my frens done CPT thru mall cart job and restaurant( i respect any job) .Well, for CP,. u have to join some college. Try some places where they offer online degrees, I think california does that. I personally I dont know, but i can ask my friends if its ur option!  Why don't u try going back to ur own university so that way, u dont need GRE/GMAT.

Good luck!
