There are very few merit scholarships available for OOS students. UCLA regents is awarded to around the top 1.5% of applicants and amounts to about $2000/year. http://www.rssla.org/about/scholarship/

I would run the net price calculator for UCLA. At the minimum expect to pay the $24K/year OOS supplemental tuition and fees and the maximum at $55K/year.
