Convert tradingview to mt4 expert advisior

Hello, I have a TradingView script and would need an MT4 expert advisor that is identical to it. It must have the same settings and make entries according to this script, with SL and TP freely adjustable, i.e., SL at the last high including additional pips or only by points. TP either on a counter signal or by points, and trailing based on candles, i.e., always calculated by candle distance (meaning that when the price makes a new candle, there should always be a distance of 3 candles, for example but this should be freely adjustable) or based on points or moving average. How much would something like this cost and how long would the lifetime be? I need the expert advisor and also the script for the expert advisor. Thank you. Please treat the script as confidential, as it belongs to one of my customers and is not authorized for distribution. Thank you.
