Pet Sitter Needed - Full-time / Part-time

This is my first time using a service like this. I'm looking for information. I have 3 Shih Tzu mom (4 yrs old) and her 2 son's (3 years old). This would be their first time being away from home. Well mannered, go out every 2 hours with snack to follow. Eats dinner at 4 p.m. no later than 5. Bathroom at 7 p.m. and then before bed at 9 p.m. Go out 6 a.m. and then the same every day. No medications needed.
