Correct me if I am wrong, but I do not believe there is a scholarship for SLS. You must make all of the payments on your own.
However, you could hold community fundraisers, which I intend to do, such as raffle drawings, selling food, etc. I'm sure the locals would be more than happy to assist with you attending a fairly prestigious summer program.
Search around for other assistance as well. You might be surprised who would provide you with funds.
