Help Caroline go to NYC summer camp

I auditioned for and was selected to attend the Open Jar Institute in New York City, which is an intensive Broadway summer camp. What I didn’t realize when I auditioned was how expensive it was going to be. I didn’t think I would be able to go but luckily my grandpa surprised me and paid the deposit for the camp. But the cost is still very large. This would be an amazing opportunity for me because Open Jar is a very renowned program taught by broadway professionals. I’ve always dreamed of going to New York and it would be so amazing to go specifically to do what I love. Any help I can get is much appreciated!
