Need help setting up home network and Wi-Fi optimization

Hi, I'm looking for someone experienced to help set up my home network and optimize the Wi-Fi coverage throughout my house. I have a few devices that need to be connected securely, and I want to ensure the signal is strong in all rooms. Ideally, you can also advise on the best router placement and any necessary equipment upgrades. Looking for a reliable and knowledgeable person who can explain things clearly. Thanks!
