Here is the code that makes a call to DB and set the scheduler time based on the results :

Also, you can call a number of API calls which sends regular SMS/emails here itself.

public void ScheduleService()
    {
        try
        {
            dsData = new DataSet();
            _timeSchedular = new Timer(new TimerCallback(SchedularCallBack));
            dsData = objDataManipulation.GetInitialSMSConfig();
            if (dsData.Tables[0].Rows.Count > 0)
            {                    
                DateTime scheduledTime = DateTime.MinValue;
                scheduledTime = DateTime.Parse(dsData.Tables[0].Rows[0]["AUTOSMSTIME"].ToString());
                if (string.Format("{0:dd/MM/YYYY HH:mm}", DateTime.Now) == string.Format("{0:dd/MM/YYYY HH:mm}", scheduledTime))
                {
                    objDataManipulation.WriteToFile("Service Schedule Time Detected");
                    for (int iRow = 0; iRow < dsData.Tables[0].Rows.Count; iRow++)
                    {
                            if (dsData.Tables.Count > 1)
                            {
                                if (dsData.Tables[1].Rows.Count > 0)
                                {
                                    sendData(dsData);
                                }
                            }
                            else
                            {
                                objDataManipulation.WriteToFile("No SMS Content Data !");
                            }                        }
                }
                if (DateTime.Now > scheduledTime)
                {
                    scheduledTime = scheduledTime.AddDays(1);
                }                   
                TimeSpan timeSpan = scheduledTime.Subtract(DateTime.Now);
                string schedule = string.Format("{0} day(s) {1} hour(s) {2} minute(s) {3} seconds(s)", timeSpan.Days, timeSpan.Hours, timeSpan.Minutes, timeSpan.Seconds);

                objDataManipulation.WriteToFile("TexRetail Service scheduled to run after: " + schedule + " {0}");
                int dueTime = Convert.ToInt32(timeSpan.TotalMilliseconds);
                //Change the Timer's Due Time.
                _timeSchedular.Change(dueTime, Timeout.Infinite);                    
            }
        }
        catch (Exception ex)
        {                              
            objDataManipulation.WriteToFile("Service Error {0}" + ex.Message + ex.StackTrace + ex.Source);
            using (System.ServiceProcess.ServiceController serviceController = new System.ServiceProcess.ServiceController(ServiceName))
            {
                serviceController.Stop();
            }
        }
    }
