Need help installing a home broadband box and setup

I’m looking for a friendly technician to install a new broadband box at my home in Ireland. The job includes connecting the modem, configuring basic Wi-Fi, setting up a guest network, and ensuring all devices can connect smoothly. Please note I have a standard UK/Ireland plug setup and would appreciate guidance on router placement for best signal. If you can also assist with updating firmware and testing speed, that would be great. I prefer a tidy, unobtrusive setup and clear explanations for any changes made.
