Babysitter For 9 Month Old

Hello! I am looking for a new babysitter as the one we have now is moving out of the state of Alaska. I have a 9-month-old boy who is very sweet. I am a working first responder mom so I can have a weird and moving schedule. I work 24 hour shifts and my husband work on AFB base working 8 hour shifts. I am a first time mom so I am very nervous having to leave him with someone new. You would have to watch him for 8 hours, 3 p.m. to 11 p.m. the days I am working. I would prefer if you have a CPR/bls or first aid certification and be comfortable with cats as we have two. Both are very sweet and mainly keep to themselves. Thank you!
