What you say is fair enough ... but who's going to pay for all that? If you're not careful you could end up paying more for the "consultancy" than you do for the "maintenance" (or the real work, if you like)!
When it comes to checking the paperwork (and that all the boxes have been ticked) ... well, the Contracts Manager (client?) can do that. But if he (she) isn't a "technical person", then he (she) will need to call upon someone who can actually check-out the kit.

OK ... it was all "once upon a time" ... in a "place far, far away" ... but no-one ever said to me:- "can you please come and check our paperwork"? It was only ever "can you take a look at our equipment, and give us your 'opinion' (proposal, whatever)"?
