Need help installing a new broadband box and Wi‑Fi setup

I'm looking for a reliable technician to install and configure a new broadband box at my home. The job includes connecting the router, setting up the Wi‑Fi network, configuring security (WPA2/6), and ensuring a stable connection throughout the house. Preferred to test speed and help with any connected devices (laptop, phone, smart TV). Please bring the necessary tools, check for interference, and provide a brief on-site guidance for ongoing maintenance. I’m in a two‑storey apartment and would appreciate a clear explanation of any steps taken. Availability on weekends is a plus.
