PineScript indicator

Hello, I am looking for a professional in PineScript. I want to develop an indicator that gives me buy and sell signals with targets and stops. I want it to have a table that shows the backtest. I want the success of the signals to exceed 80% and a very high win rate. I do not have a strategy. I want complete development and for it to be a professional and distinctive indicator that does not redraw. The most important thing is to do a very deep backtest to make sure that its signals are very successful. How much will it cost me? Please attach the details if you are interested. Thank you.

I attached examples.
