Pet Walker - Full-time / Part-time

I have 3 dogs. One 9-year-old named max-he is a barker but INSANELY friendly and loves love. Fully house broken and uses a bark collar. We just got 2 puppies-Penny and Tammy, both 7 months old, today, who are still training with potty/crate/steps etc and dont want to leave them home alone yet. This will be a few days a week when my husband and I are both working, hours typically 6-2 but flexible because I dont mind leaving them in a crate for a bit if 7-1 or something would work better.
