Need help installing a home broadband box and setup

I'm looking for a courteous technician to install a new broadband router and ensure the Wi-Fi is working throughout my home. The job includes connecting the modem, configuring the wireless network, linking devices like a laptop and smart TV, and testing signal strength in a couple of rooms. I’d prefer someone who can explain basic settings in simple terms and can follow safety guidelines. If you can also assist with connecting a few smart home devices, that would be a plus. Location is in Ireland, and I’d like the appointment to start in the morning if possible.
