I hired someone to clean my house the other day and I wasn't going to be home.  But they had good reviews on Facebook.
I hired someone to clean my house last week!

Did they do a good job of cleaning your house?
assistant
It ended up yes, I was worried though because I wasn't home.
user
That would make me nervous, you never know if they are looking through your things. 
assistant
Yeah but they had really good reviews and were reccomended to me by my neighbor.
user
That helps a lot with the peace of mind. I am glad it worked out well for you!
assistant
I won't be so worried next time.
user
It is nice when they can build up that trust with you!
