Cable re-management

Hi, I wondered if any of the NANO's (Specifically NYCNANO's) have ever brought in another company, or offered as a service to the general world cable re-management. I know Hugh O'Kane is a big place that does it, but I'm looking for said services in NYC. I have client datatel closets that REALLY need color coding, cables cut to length, A-B labeling, etc. For an added bonus, they would potentially be able to build out an entire FLOOR of a building from scratch. Private replies please, will summarize to any who ask. Thanks, Tuc/TBOH
