TradingView Pine Script Developer - creating Alert from Strategy

I am looking for a freelancer to develop a TradingView alert for me in Pine Script. I have a strategy based on the TSI indicator. I need an alert that will send alert emails at the same time TSI puts the Buy and Sell texts on the chart. The chart is in one time frame and the indicator is in another time frame. The Buy & Sell texts are placed on the chart without any issues but I can't get alerts to correspond. Successful candidates must have prior experience building custom TradingView strategies using Pine Script.
