Unpaid internship in consulting postgrad VS entry level job w/ good salary

I'm from Morocco, where consulting is a very interesting area to work in. I am freshly graduated, I have a Master's degree in Finance and banking. Now I have an offer for an entry level job as a business developer (which is something that has nothing to do with my area of specialization, or with my professional ambitions) but the salary is very very interesting, and as a freshly grad, I can't find it elsewhere (even in consulting). At the same time, I have an internship offer in a big advisory firm but I have no clue about what will happen after the intership. Now I'm wondering if the BD can cause me an issue on my Curriculum Vitae if I'd like to get back to consulting. Should I take the unpaid internship + uncertainty about the future in oder to have that name and that experience on my Resume? Or take the job, be financially stable and keep looking for a job as a consultant, even though I don't have experience as a consultant? In this case, are my chances moderate or low? (I have 4 internships, 3 are in corporate finance, 1 is in risk management).
