I am bidding on a very small flagstone patio area, well an area where a bench is going to set aprox. 48 sq. ft., where in greensboro or asheboro,nc can I get flagstone for such a small area. What would you charge for this if they are also doing a good size landscape install. Also right below that patio is going to be a small retaining wall aprox. 7'x2', what would look good with the flagstone?
