We've been contemplating on hiring a baby sitter. But the thing is, we don't know anyone. Is it safe to go to agencies and hire someone who you don't know?

You may ask around in your neighborhood if there is any nanny staying nearby your house. Also, it will be convenient for you to send and pick up baby from nanny's house since it's within your neighborhood. Hiring a nanny is based on luck too. If the nanny is willing to communicate and follow your instructions, mostly likely your baby will be in good hands.
