Water Polo

I would like to raise some money for my son to participate in a tournament that is fast approaching, for water polo. I am a single mom, and while try to keep both my kids as active and involved as possible, I quite often fall short. I truly believe that a child that participates in activities outside of school is less likely to wind up being a drain on society later in life, as well as having greater respect for persons in a higher position. I do not push my kids into participating in any activity and work very hard to keep them active in all they love to do. Due to my father's very recent passing, I have come up more short than usual and am reaching out to you. Please help.
