Occasional Reliable Sitter

Seeking an occasional sitter for days when both my husband and I are working. While I am typically a stay-at-home mom, I still take on clients occasionally. Both my husband and I work in the film industry, which often involves 12+ hour days. We need someone who is flexible with work days and comfortable with long hours. Must be okay with a large, friendly very low maintenance dog. Applicants who are reliable and reply to texts in a timely manner need only apply. Thank you.
