Pet sitter Job in Yucca Valley, California

I have a 4 month old puppy and a 2 year old dog. When I go out of town I need someone to come over and help with my dogs. I haven't figured out exactly what I need but most likely I will need someone to come let them out in the morning..make sure there is good and water for them outside. .and then later to bring the dogs back in for the night. I am consudering leaving them outdoors the whole time as I do not have a doggy door...but I need some advice on best way to do this too.
