Summer camp /financial help. Suggestions needed

Hi everyone! I am trying to adopt a couple of children in foster care. They are supposed to move in June for the pre-adoption placement. I am a single mother (or would be) and they said there will be no financial help until the adoption is final (at least 3 months later). So I am wondering if there is any help available from Churches, youth groups and other so that I can put them in Camp over the summer. I obviously cannot take so many weeks off work and without financial help, it is not possible to pay so much for summer camps. Do you have any tips? or should I push their move until August? Thanks for any input!
