single mom who's desperate for help

I know this doesn't seem as urgent as some other posts on here but I'm desperate. I was dropped from my homeowners insurance because my roof is too old. I was approached by a roofer that said they could help. They assisted me in filing a claim before I was actually dropped, but I still have to pay my deductible. I'm a single mother of an autistic son and it takes all money to pay for the services his insurance doesn't cover and I can't come up with $2,500 by the end of the week. If anyone could help me out at all I would be grateful beyond words. I'm already crushed that my son will basically not have a Christmas this year, and I'm afraid of what will happen to us financially if I can't get the roof fixed and avoid force-placed insurance by my mortgage company.
