In home computer assessment?

Hey, can anyone recommend a service to come to our house and evaluate our Internet and devices? Things run slow. Not interested in advice, just someone to handle it. LSU area.

UPDATE: Hmm, I see my poorly worded post has resulted in sarcasm ... To be clear, I didn't want someone replying with "check your data cache!" "Reconfigure your thingamajig!" I'm too tech illiterate. Hope this clarifies things.
