CR6, CR8, GAB.....What to use and how much?

Hello all from Clarksburg, MD!

I badly need more parking space and have excavated two separate spots. Each about 20'x20'. So far I've excavated 4-5" by hand (and find myself looking at Bobcat prices) and framed them with 4x4. I plan on filling with almost all base material and compacting a lot with a jumping jack tamper I found on good ole Craigslist...then topping off with a thin layer of 3/4" gravel I already have.

Is 4 inches of base material enough?

Whats the worst that could happen if its not?

Which base material should I use?

I've been quoted:

CR6 at $16 / ton

CR8 at $40 / cubic yard

GAB at $17.50 / ton

Are all these materials similar?...gravel with dust mixed in? I need to knock this project off yesterday, any input is greatly appreciated.
