Hi,
just a brief note. You mentioned that you hold a CPL issued by NAA NZ. The highest level of pilot certificate issued by the FAA (US) based on a foreign license is a PPL. See link below:
eCFR ? Code of Federal Regulations
For any higher grade certificate/rating (e.g. CPL/IR) the person must take and pass the respective FAA knowledge test and checkride.
Since you said that you intend to look for a job in the US afterwards, you probably must get a stand-alone (not based on a foreign license) FAA PPL and built up on that. Which means that you have to take the FAA PPL knowledge test and pass the checkride.
I can't help you with flight schools in the SF bay area, but I guess there are folks around here you can help you with that.
