You have a GC, that's added advantage among others, and you have Master's Degree in Information System, what a combination? you should have already been in market, go to any IT consultancy, get a project, don't worry about pay for first project, even 30-35 is ok, since you have GC they should pay little more. there is no good and bad marketing, just get experience anywhere for first one then from second you will be able to decide.
