Dingle to Dublin early morning transportation?

Long story short... we are visiting Ireland in May, and we have a unique opportunity for an event in Dingle the night before we fly out of Dublin. We would need to find transportation from Dingle to Dublin the morning that we fly out of Dublin, Ideally leaving at 5am or 6am.

Someone quoted us a private driver for $800, but I'd love to entertain any other offers or services that someone may know of. Thanks.
