I don’t normally like to recommend do-it-yourself when someone asks for professional help, but depending on your situation, this could be an unusually cheap and easy DIY project. If you have your router close to your TV, you just need to buy an Ethernet cable from almost anywhere– even the hardware store in the Junction has them– and connect the cable to the jack that looks like a big telephone jack on the back of your TV to the same jack on your Wifi router. That’s it, and unless you have something crazy going on, your TV will detect the internet automatically.
If you still want a pro or want to do something like run a cable behind a wall, then I think that even the worst electrician could do it in 15 minutes.
