Awning for rescue

We're a small exotic pet rescue.  We clean the animals cages with a water hose and utility sink on an uncovered patio.  It gets hot and when it rains we can't work. Sometimes I will work in the rain though because the cages need to be cleaned.  It would really help our volunteers to have an awning covering the patio so they don't have to stand in the sun.  Please help any amount matters  no matter how big or small your donation.
