Soft Proofing in GTA

I am looking into soft proofing for practical appraisal purposes on a print shop floor.

I've been doing a little looking around, and we already have some basic software/hardware (i.e. i1 Pro and i1 Match), but I really want to get a feel for how effective it is and what sort of monitors/setup we would need.

Anyone in the GTA using soft proofing on their shop floor? Would you be open to sharing how you set yourself up, or better yet, a visit?

Thanks,

T
