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?

It's the same as hiring a maid. Most people hire maids from agencies without knowing the maid personally. The benefit of hiring a baby sitter from an agency is that you can get to pick and choose the nanny. The agency can find a suitable nanny based on your needs. It depends on the babysitter herself than the agency. You can ask the agency for an experienced babysitter and take a look at her portfolio before deciding.
