indicator for my mac analysis

I need someone to build an indicator for my Mac analysis. The type of analysis I am looking to perform is technical analysis, and specifically I need a moving average indicator, which needs to be visually represented in a chart. I already have a version of what i want but i can not develop it anymore with my limited pine script abilities. I want to install several options within my indicator that seem fairly simple but i don't know the pine script code. The picture show the current version of my indicator. I use a moving average cross strategy. 5 /100 with the cloud with cross over signals. The white line is 200 SMA. I would like to customize my current indicator to include the 200SMA as an option to turn on and off. Second, i want to have an option to be in bullish mode or bearish mode. Meaning that if in bull mode only buy signals will show. Bear mode only bear signals will show. Lastly i want to install an expiration. I want the indicator to shut off and not work every 3, 6 or 12 months. I plan to share it at the highs school in teaching kids and want it to expire after a period of time but can be renewed with a new code. I hope this helps. Thank you
