Going in August sucks for the money reason, it would just annoy the hell out of me paying 900 quid for an economy flight to LA! You've done very well on the car hire though, £520 for 3 weeks on a speciality with Hertz is bonkers, you sure you've got all the insurance etc included?
Also consider doing it the other way round only for the reason that when you do the Pacific Coast Highway if you go up rather than down all the scenery is the other side of the road!
Careful also with the Grand Canyon - helicopters are banned from the Canyon so if your trip offers that you are going to the rubbishy 'West Rim' instead. Avoid that!
