Cybersecurity mobile phone and home network

As a homeowner and mobile device user, I am looking for assistance with cybersecurity measures for my small home network and mobile phones. Specifically, I need protection from malicious intrusions, such as firewalls, antivirus software, encryption software, and MAC spoofing prevention. Additionally, I have specific vulnerabilities and concerns I would like to address and need an assessment to determine the threats present. My home network includes 1 to 24 max devices and 2/3 mobile phones. I am looking for an experienced freelancer with the right skillset who can provide robust safeguards for my home network and mobile devices.
