Have you checked with your local vets? Sometimes they need someone to keep the rooms disinfected after each visit, cleaning the cages, making the animals comfy after surgery, watching them during recovery and most vet clinics now offer grooming services so you might get lucky there.
You could always run an ad for pet sitting services, many homes prefer to hire someone to live in or go to the house a few times daily when they go away...I know I never boarded any of my dogs and never will.
