Need help setting up a home network and security

Hi, I'm looking for someone experienced to help me set up a secure home Wi-Fi network. I want to ensure all devices are connected properly and that the network is protected against unauthorized access. Ideally, you can also assist with configuring parental controls and optimizing the network speed. I have a basic router but need guidance on the best settings and possibly some hardware recommendations. Looking for someone reliable and knowledgeable who can explain things clearly.
