There are some nice apartments in the Wildewood area around Polo Road, which is a very easy commute to the Dentsville area. I don't know the price range but I think a 1 bedroom for that price may be doable.
Do be careful around 29223 and the near Northeast/Dentsville/Percivial Road area, though, as there are some sketchier apartment complexes in the area, so don't fall for low rents automatically.
If he is willing to drive a bit further out into the Northeast, the Reserve at Lake Carolina, on Hardscrabble Road, is a good apartment complex (at least it was when we lived there for about a year when we were building our house). This would still be a reasonable commute.
