Need help installing a home internet box and configuring Wi-Fi, Dublin

Hi there, I'm looking for a friendly and patient tech to help me set up a new internet box at my flat. I have basic knowledge but I’m unsure about connecting the modem to the router, configuring Wi-Fi, setting up a secure network name and password, and ensuring devices like laptops, phones, and smart speakers connect smoothly. Please include guidance on firewall settings and parental controls if possible. I’d prefer someone who can work around a modest living space in Ireland and explain steps clearly while doing the work. Availability on weekends would be ideal.
