Drive time from Wilmington is 4-5 hrs. depending on where in OBX you are; the ferry takes just as long. OP might have better luck inquiring in Norfolk/Hampton Roads/VA Beach and see if someone there is willing to make the 2-3 hr trek.  

There may be a handful of BP postings, but nothing I could vouch for. If you're lucky you might catch a legit provider on her OBX vacation, but for the most part there's no action there.
