Please be aware that variation of knowledge, helpfulness, professionalism, competence, etc...are huge between consultants, even more so than with CB auditors. So, do your homework in the consultant selection process VERY CAREFULLY. You will need to find someone who can make "meaningful interpretations" of a management system standard that was developed for aerospace flight hardware and apply it to a service organization providing "test services". The applicability and interpretation of the requirements to your product, what is a service, can create mind numbing discussions and, if not done properly, will create bureaucracy that will add no value to you, your customer and no other stakeholder, but might exist just because a consultant thought that the CB auditor will want to see it.I think getting a consultant to start working with us will help significantly.
Just to give you an example: Can you properly justify non applicability of service design and development? Let the fun begin....
And, without a question, good luck to you. Your few posts show already that you are an intelligent, well intended person.
