Need help installing a new broadband router box in home

I'm looking for a friendly technician to help me install a new broadband router box at my home. The setup will include connecting the modem, configuring wireless SSID and password, updating firmware, and ensuring a secure Wi-Fi network. I prefer minimal downtime and can provide the router's model number and any necessary login details. If possible, please check signal coverage on a couple of floors and suggest any simple optimizations (like placing the router higher or using a mesh extension). I'm flexible on time but would like the job completed within a single visit and within normal business hours.
