The Webster County History book (published 1980) says it is about 4 miles from Richland, GA. If you leave Richland on Nicholson St., east, you come to a road on the left by a small house (County Road 123). Down this road is Enterprise Church. The cemetery should be on the right, I think about half a mile up from the church (I don't have the book with me right now).
Are you researching the Nicholson family??
