I am happy to drop an RFP in person at a location which can somehow substantiate the existence of MediaG3 and their offering. Any office or warehouse with their equipment and a technician or two will suffice.
I have already met with two telecom providers, 1 fiber provider and a security company, all on their turf, and had a walk through their warehouse and/or Network Operating Centers (NOC's). They were all happy to oblige. Any respectable, valid business would see this as standard protocol.
They all provided a breakdown of service offerings and an SLA template. They have also offered to provide references, which will be named in the response to RFP.
