Find a local network troubleshooter in Blacktown

We are the new owners of a business located near Blacktown train station. There is an active Telstra internet service feeding our office. I have established a new connection with Superloop to replace the Telstra connection. Live connection was confirmed by Superloop. I wish to hook up the now active Superloop service to our network on WAN2 to test prior to decommissioning the Telstra line on WAN1. The internal NBN box is not in the same room as the networking equipment. The networking hardware is handled by the Cisco Meraki cloud service. I have access to this account. We hope to have this completed early next week. I appreciate your consideration.
