Send Riley on an Adventure of a Lifetime

Riley has always worked hard to earn everything she has gotten. She is an honors student who is currently enrolled in both high school and college courses so that when she graduates from high school, she will also have her two year transfer degree. She earned $3000 when she was 13 to go on an educational trip to Costa Rica. She volunteers two hours everyday in the special education class at her school and planned and put on a daytime prom for the special ed kids and their peers from three other high schools. She has worked for friends and family to earn money for school clothes, school trips, and cultural outings. 
Riley has dedicated much time and effort to playing in the band. She started playing Baritone (or Euphonium) in 5th grade (pictured below) and put a great deal of effort into becoming the best that she can be at it. As such, she has been invited to play with the Oregon Symphony Orchestra, has been accepted into the Oregon School Association's Honor Band, is an active member and secretary of her school's chapter of the Tri-M Music honor society, and has been nominated by her band director, Mr. Lee, to participate in the Oregon Ambassadors of Music European Concert Tour. She would be touring with about 200 other Oregon band students, for 16 days, through 7 countries.
Just one obstacle: The tour costs a great deal more money than she has ever raised before. 
Much as I would love to foot the bill for this amazing experience, as a single parent I can not afford to do it alone.
Riley has already started working to raise the money to pay for the trip. I would love to make it just a little easier for her.
Please help me give Riley the greatest gift ever: The experience of a lifetime, playing in a symphonic band tour of Europe!
