You can have the pastor of your church organize a car wash for you. Also,your church can take up a collection,during morning worship. You can have a yard sale,and also sale baked goods,during your yard sale. Talk to the school administation,in your city,and explain the situation to them. I'm sure they will think of something nice to do too. If the family of this child does not have insurance,then they can also contact the office of "Family and Children services",to apply for Medicaid benefits. If his condition is as bad as it sounds,then the family will not be turned down. (Much Prayers,and Good Luck)
