Help my son go to yeshiva

Hi everyone. This is very unusual for me. I am stuck in a situation. We have a yeshiva that will enroll my son but they are asking for $18,000.00. We cannot afford that. My son was extremely close with his sister Rivka a"h" who passed away 3 months ago. He is having a bit of a hard time. He needs to be in school as he is only 15 years old. It is not healthy for him to be sitting home playing games all day long. He is a great kid who can do well if given the chance. It is uncomfortable for me to ask people for help but I feel I have no other option. If you can give anything at all to contribute to this cause we would be greatly appreciative. I wish you all a healthy happy new year filled with only nachas and simchas. Please feel free to pass this on to others.
Be well,
Leah Sheen
P.S.-You may be able to use Maaser money for this!
