According to
http://greenvilleonline.gannettonlin...careerbuilder/, there were 62 call center job listings in the last 30 days. This number will probably increase when the school year starts. I know that Teletech here is a large call center for UPS, there's a regional call center for the cable company, and I'm sure there are plenty of others. Radio I don't know a thing about, except for the fact that there are plenty of radio stations!
If you're interested in finishing your degree, there are many, many colleges convenient to Greenville. We even have a place called The University Center in an old shopping mall where you can take classes offered by schools all over the state.
Check out Greenville; it's a good place to be.
