First you'll need to be admitted as a transfer student. The good news is that the UNC system treats in-state and out-out state transfer students the same for admission purposes so you won't be at a disadvantage. I knew a LOT of people at UNC that got in as transfer students who were flat out rejected as freshmen so there's definitely hope. The bad news is that you'll have to pay out of state tuition. Out of state tuition at UNC Chapel Hill is about $20k/yr while ECU is about $15k/yr.
Another option for a BSN which I'm surprised no one has mentioned, although I shouldn't be because few people are familiar with Wilson, is Barton College (formerly Atlantic Christian). Barton is IN Wilson and tuition is equivalent to the out of state rate at UNC. Unlike UNC and ECU, Barton is private so there is decent chance that they'll award you some financial aid... I wouldn't hold your breath waiting for financial aid at either of the state schools.
Anyway, enjoy your visit to Wiltson. Once you hear a local pronounce the town's name you'll understand why I put the T in there.
