Resume for summer internship w/ low GPA

Hi there!

Before I start throwing my doubts, I want to thank you all for this great community it is. I've been reading you for over a year and I find this forum very productive with very interesting posts and people's experience.

Once this said, I'm going to apply for a summer internship in the US (I'm from Barcelona, Spain) next year and since it's my first application for an IB I'm not pretty sure wether I'm doing things right or not.
My main problem when applinc for these banks is my LOW GPA and not coming from a target university (University of Barcelona). Not a Harvard or a Columbia. Though, I describe myself as a very enterpeneurship person and got involved into the business world since my freshman year.

I've founded a very strong financial organization on my first year of college and last month created a new business, related to the financial world, with an Ex-Manager of a well-known financial corporation here in Spain.

Though my problem is still my GPA (a 6.2/10, that I guess it would be a 2.5/4). So I've got few questions:
a) Do you think I've got any chance to get into any important IB?
b) Do you think I should put down my GPA on my resume?
c) Do they really throw off your resume if they don't see your GPA anywhere in the resume?

And this is my resume (i know there's few typos, still haven't checked them out):
