Please help my 16 year old nephew, Jesus, pay for his Stanford High School Summer College Program tuition

I am an art teacher at an elementary school that has been teaching for 16 years. I come to you for help to assist my nephew, Jesus Rivera III; to fulfill his dream in becoming a student for Stanford University. Jesus Rivera has just been accepted into the Stanford summer high school college program at the age of 16 years old. (A copy of the letter can be viewed HERE). I feel that this opportunity should not be let to pass due to financial reasons. He has been interested in attending Stanford from the young age of 13 when he had his first visit to the Johnson Space Center in Houston, Tx. He met an engineer there, that upon inquiring about his scholarly background, went to Stanford University. This gentleman completely caught my nephew's attention. It was then he was inspired to attend the same prestigious university to become a mechanical engineer. At the time, and even now; he didn't quite understand the cost of attending this university. My nephew just continued pushing himself into meeting the rigorous academic entry requirements.
He began applying for the Stanford summer high school college program in the beginning of February. Upon receiving his acceptance letter, it was then that the cost of the summer program was discovered. The amount I am asking help with is $13,000 just to cover the tuition and fees for attending the program. (The tuition fees can be viewed HERE.) Our families are willing to work together to cover his additional living expenses, flight and transportation, while fulfilling his educational dream.
This would mean so much to him, since he would be the first one from his father's family's side to attend a University, considering he's breaking the chain by furthering his education more than anyone in the family ever has. This is a great accomplishment for his age, family, and cultural background. Not only as an educator but as his aunt, I am extremely proud of his educational accomplishments thus far, and his drive to continue his education. I see great things coming for him in his future. He just needs that financial start to help him on his road to success. Unfortunately, financial aid funds for the High School Summer College program have been exhausted, therefore we are seeking your help to make this possible. He just received his confirmation letter of acceptance last week. We met as a family to discuss methods of helping him out. It was then we decided to come to you and see if you could find it in your heart to help him in any way possible. According to the letter, the deadline is fast approaching, March 26, 2016! We know it seems so rushed, but imagine our surprise when we discovered the deadline date. However, we believe anything is possible, and we will not give up hope.
Education is very important. When an opportunity to attend a school with the lowest acceptance rate in the entire United States comes along for someone like him, who has proven through hard work and dedication, inspite of financial means or hardships, deserves the same opportunity as those who have better financial means to attend.
It is with great appreciation and gratitude for your time and understanding of his situation, that I would like to thank you from the bottom of my heart for helping him further his education by attending a well renowned school, as well as letting him continue his dream.
