.Need an urgent consultation with a cybersecurity specialist of hacker!

Need to consult a cyber/network security specialist or hacker in order to get my network of devices unhacked and prevent any further hacking. My entire home network of personal devices has been hacked. The hackers are my neighbours. They can view my screen. They can hear me even while speaking quietly. They have access to my files. They can control my devices. I need a consultation to get an estimate of how much work needs to be done and how much it would cost, for me to decide whether to proceed or not seeking help from your services. My maximal budget is $300. I need technical support, guidance, and advice on what to do to resolve my hacking issue.
