[Highland Park] Looking for a ride service for my children

Hello, everyone, I was wondering if anybody was aware of a good, reliable service that will essentially be a delivery service for your kids? I've got a couple of times this summer when I and my husband are both busy at work, and one or both of my sons will need to move from one summer camp to another. I'm pretty sure that I had heard about a similar service in a previous place we've lived, but can't seem to find anything for Pittsburgh. Thank you in advance for any leads you can offer.
