Pine Script for TradingView Chart

I'm looking for an experienced Pine Script programmer to create a version 6 code for TradingView. This code will implement the following:

- Draw a Simple Moving Average (SMA) with a period of 20 on the main chart (overlay = true).
- Draw two Exponential Moving Averages (EMA), one with a period of 5 and another with a period of 25, below the main chart (overlay = false).
- Draw an upward arrow if one the the two conditions was fulfilled:
a. If the last closed candle's EMA(5) has crossed above EMA(25) while the closing price of that candle is already above the SMA(20), or
b. If the closing price of the last closed candle is above the SMA(20) while the EMA(5) of that closed candle is above EMA(25).

The default colors for the indicators are:
- EMA(5): Blue
- EMA(25): Orange
- SMA(20): Blue

In addition, I need the script to send a pop-up alert whenever these conditions for the arrows are met. The arrows can remain as the default style.

Ideal candidates for this project should have:
- Proven experience with Pine Script and TradingView.
- Strong understanding of technical analysis and overlay indicators.
- Excellent attention to detail to ensure all conditions are coded accurately.
