Beat The GMAT a GMAT & MBA community

Hi,
I am from Iran, and have faced very hard decisions in very short time.Please Help.
I have applied mostly for MS marketing.
and I have been applied to the following programs:

- Columbia Business School----No Scholarship-Graduate Assistantship
- University of Rochester-----10,000$ Scholarship-Graduate Assistantship and on campus jobs
- ERIM Erasmus Research Institute of Management (Erasmus Rotterdam)-Mphil program -low tuition and awards
- University of Cincinnati-----6000$ scholarships and on campus jobs
- EDHEC MiM with Marketing Management Specialization-----8400euro scholarship and on campus jobs

Well, seemingly the Columbia is by far the best but, the tuition is very high.
I am thinking of Private loans, any one has any ideas about them for international students?
Also I think of the post graduate career placement.Any comments and suggestions is welcomed.
