My realistic odds. Goal Silicon Valley Start-up

Hi, I am from Spain and my goal is to be hired by a Silicon Valley Start-up or build my own one. Technology is my passion, But I discovered too late. I would like to switch my career from a family home textil import business to High Tech business.

I have 9 years of experience, 6 as a second behind the CEO.
GPA: Business administration degree in a local university. 2.99 (I worked and studied in my last year)
GMAT: 650
TOEFL: 107

I know the top b-schools that can open the silicon valley doors (Stanford, MIT, Haas) but with my scores, it is unlikely I get into, so I am looking for other b-schools. Can you recommend me a few ones?

Thanks in advance
