i typically do not handle rental properties. But I did take a look at availability for you and found only 2 homes in the entire Triad with 5BR/3BA available for rent. Neither was in the area you described, and both were significantly higher rent.
Your best bet is likely to deal with a company that deals specifically with rentals. Often, they do not list the homes they are working with in the MLS due to high turn over and the cost factor versus exposure to renters.
Best of luck,
