statistical sampling plan

I have a lot size of 120 cases.
Each case contains 10 pieces so the total number of pieces is 1200.

I want to take a warehouse sample to see if my defect level is less than 3%.
I am assuming that the customer will accept the product 95% of the time if the defect level is less than 3%.

What could be my single sample size and reject number ?

If I used double sample plan what could be my sample 1 and 2 and associated reject numbers?

Do you have any industry specific expectations such as c=0 in the automotive industry? AQL or LTPD expectations?
