You should really be posting this on NextDoor or local forum/subreddit, & get some referrals at the same time.

That said:

• Single story home implies you at least have an easy cable run in the attic. Depending on construction basement/crawlspace could be easy too (unless it’s a slab).
• Low voltage contractor is generally a better bet than electrician for the termination and materials choice. Unless you have the networking knowledge and social skills/gumption/experience with contractors to micromanage a electrician into do the right thing (and you need all those skills, even though I can research the technical info in more detail than contractors on some types of projects I cannot always convince them to do it the way I want)

Hang in there. What you’re looking for is a solved problem, the only issue is in figuring out the path for you to get the necessary knowledge/expertise to address this.

A lot of the people on this subreddit likely have training in picking hardware for dayjob (whether in networking or something else), and simplifying/decomposing the problem to reduce the exploration space.

You might consider also asking around friend network or on NextDoor for some referrals / people with the DIY knowledge. I’ve been happy to consult for free for friends.
