Would you consider Uber or Lyft? Both options will be fairly cheap and it will be super easy to get one at that time. Traffic will be a non issue at that time on a Sunday so your ride will be under an hour.

Otherwise, you can choose really any of the local shuttle services: Super Shuttle, Prime Time, etc. They are all about the same, quality wise, although the shuttles have the annoyance of making multiple stops before you actually head out of the area.

Personally, I like Uber. I find it cheap, efficient, and much better than doing a shuttle service.
