What is the best type of auditing scope for a distribution center?

Good morning!  

I am curious to know your thoughts regarding the best type of auditing scope for a distribution center. 

Background: We are opening a food storage and distribution center in another state for frozen, refrigerated and ambient food products. My current site is also a DC, but primarily is a frozen veg/fruit repacking plant which is SQF certified FSC 14, 25, 26.  I am looking to get our new facility certified/inspected in some capacity. 

SQF is not the appropriate fit for our new site as staffing and resources will be very lean, i.e. no SQF Practitioner and alternate. Although I know I could get the site certified, I honestly do not believe the program would be properly maintained.

This model also needs to be duplicated for additional DCs that will be opening in the near future. I am exploring different GMP schemes; AIB Consolidated GMPs, MXNS's DC Audits, etc. and wanted your opinions on accredited vs inspection audits. 

I have only operated within the world of SQF; so I see similarities between SQF and the GMP/DC inspections, but as far as customer expectation go, is a GMP inspection generally seen as adequate? 

Thanks everyone! 

The company I work for is currently adding a DC site.  We are utilizing BRC.  They have a "storage and distribution" standard that fits the need.  Our other facilities are also BRC certified, so that helps us keep costs down to a point.
