I have used Company Car & Limo for car service for my boss. Found them via their Yelp page.
My boss reported to me that the driver was great and professional. Going to be a repeat customer from here on out for transport to/from the airport.
Pricing for 1 passenger in a private car is reasonable. They offer the ability to pay in advance so I can take care of that and my boss doesn't need to be concerned with it.
The couple of people I've talked to in dispatch are calm and easy going.
