Employee parking is $55 for most lots at LAX. The Cargo Lot (F) is $75, it is covered, but does not have a shuttle to LAX. Its an easy walk to the terminals though.

And by telling us where you live might help us. Check to see if there is a flyaway bus route close to you. And the light rail is an option as well. But without knowing where you are coming from, I don't know what replies you expect by simply providing an avg. uber fare.
