My chances for getting into Consulting?

Hi,

I am a freshman at an Eastern European university.
Although I am a freshman, I have had some work ex as well.
Between school and university I had a 3 yr work stint at several major NGOs and a start-up of my own.
Hence, I hopefully do not want to land a very entry-level position.

I'm greatly enthusiastic about consulting , but think I don't have enough knowledge because of lack of peer group here. WSO Forum has been the only real source of information for me. I've recently started networking, but amid the time of application period, I get almost zero responses.

I'm interested in a Summer Analyst position at all Big 3 and any major consulting firms in Europe and United States.

Please provide me with as many recommendations and suggestions as possible.

1. What can I do to maximize my chances at landing a Summer gig?
2. What can I do to make my Resume even more stronger? Pls have a look and criticize if you find something not right.

Any pointers will be truly welcome.
Thanks!
