Help with networking

QC’s current campus includes two buildings. A small headquarters (HQ) that houses the office staff: President, Sales, Accounting/Billing, R&D, production management. Currently there are 15 people working there. The production building is approximately 65,000 square feet. A portion of the building serves as shipping/receiving and houses the three order entry personnel that are present for 1st and 2nd shifts. QC recently secured two relatively large long-term contracts. They will need to expand to provide sufficient service to these customers. Management has secured TIF funding for a plant expansion about five miles from the current location. They plan to keep management at the current headquarters, keep some production (smaller jobs) at the current facility, and move most of the bigger work to the new, larger production plant. Management has realized that with a larger production facility and bigger orders, they needed to upgrade their technology.
