Pet Sitter Needed - Full-time / Part-time

I have 4 guinea pigs that will need water refills, food refills and of course to be told they are very good pigs. They don't have any special health needs and all their supplies will be available. I just want someone to come every other day and make sure their room is a comfortable temp and they have their food and water. Maybe 30 minutes of time if you count petting them.
