Pet sitter Job in Neenah, Wisconsin

I have never done this before, altho I have one time had my dogs at Country View Animal hospital for boarding for my son's out of town wedding. I am planning on going to Texas from Aug. 11th till Aug. 16th. I was just wondering how much you charge to dog sit? They can stay at home where they're comfortable, but need to be let out, fed, and get some attention. Can you give me an estimate on what you would charge?
