Guinea pig need heat!

Woke up today to no heat.....  the piggies are snuggled down in straw but the furnace guy says it will be $1200. It will be addressed because it is snowing outside but it wipes out every penny either of us had.... This has been a super tough year financially for the shelter and with my husbands hours being cut, I am experiencing major health issues and now my moms who is dying.... well I can not dig another penny out of anywhere. If you can help....we appreciate it.
