Electrician

Good morning- I have been trying to find someone to put our 42" HD TV on the wall. I would like the cords to go either through the wall or in a concealed box. However, I am having difficulty in finding 'who' would do this type of job. Today, I am told an ELECTRICIAN would be the person I need. With that being said, can ANYONE please recommend a good, reliable electrician that you have used? Also would help in knowing which electricians NOT TO USE! Thank you so much! Kathi Farragut Street
