            response.myPotentialCust = findcust;
            string jsonEmp2 = JsonConvert.SerializeObject(findSiteLocations, Newtonsoft.Json.Formatting.Indented);
           return Json(JsonEmp2,JsonRequestBehavior.AllowGet);

        }
    }
    catch (Exception ex)

        response.Result = "FailedGeoLocations";
        
        return Json(response, JsonRequestBehavior.AllowGet);
    }
