Uni-block Preperation depth?

I am about to lay a 10x 25 feet uniblock pavers ( 4x12 brick size) under a deck. I suggested bigger blocks but she wants to match existing.
It will eventually be a rather dry area. so heavy moisture is not a issue.

For foudation prep work, I was suggested to use a total depth of 12 inchs, 2/3 thirds item 4 (heavier gravel ) then top off with 1/3 crushed sand stone.

This is for a friend willing to pay me. How do I give them an idea of time involved ? I will ask for an hourly rate but time is the real tuff thing to figure out? I will have help in digging but I pretty much know how to do all else ( for a level job)just worried about letting them know what they are in for?

PS will put a slight pitch away from the house

SO I guess my question is am I overdigging? OR overlooking anything?

4-6" of crushed base is more than adequate for a patio.
250 sq ft price could range from $2000 - $4000 depending on pattern, amount of cuts, cost of pavers.
