connect speakers and internel

I'm looking for someone to help set up a wired connection between my multiple speakers and the Internet. I currently have more than 8 speakers that I need connected. It is important to me that this connection is reliable and secure, as the speakers will be playing music throughout our home and we want to ensure that the music sounds great without any interruptions. Thus, the person I hire must have experience in connecting multiple speakers and the internet with wired connections.
