I see that you have an Arthur Murrays and a Fred Astaires in Greensboro, but since you wanted something more reasonable in price...

My list shows nothing else in Greensboro, but perhaps there is a city close by that might have something. Since I'm not familiar with SC, you'll have to help me by tellingme if any of the following cities is within reasonable distance froom you:

Fayatville, Hendersonville, Nags Head, Durham, Charlotte, Asheville, Elon College, Raleigh, or Forest City.

Let me know.

I am not too familiar with places to take lessons in dancing in Greensboro per se, although the Piedmont chapter of the USABDA holds its monthly dances just off I-40 at Greensboro. You might want to check into that. I will try to find more information for you later, but you can probably just do a search for USABDA in your area to help you with that.
I am aware of a studio in high Point that has a good floor, and a very good instructor. Didio Barreras comes there often to give private instruction, and Dan Calloway and Silke also fly down from DC every once in a while to give private and group lessons. So whatever be the level of your dancing, you might get what instruction you want there. I will have to find the name for the studio as well, because it slips my mind at the moment.
Well, I have obviously provided scant information, but you have the leads and hopefully can find what you are looking for.
Good luck. Ciao.

Sriram.
