From Binary Indicator To Sending Signals

Hello coders!

I'm still searching for a very good solution to sent signals to potential clients without the risk that the indicator could be hacked/decompiled.

I've coded my own indicators and those are optimized for each symbol, TF, different expiry times and different tradingtimes. It is very important that the automated signal sends a message by alert instead of indicator-rules.  

I'm not sure what the best method would be. Maybe some script that sends the messages to email & notifications or some kind of client EA where the client can setup their own alerting options.

Either way, the solution must be secured and easy to add or remove clients. I know there are some solutions on the web, but i don't need copytraders with all those functions. The client just need to receive my alertmessages on his MT4 terminal, email and/or push notification on his mobile once i've added the client. 

See screenshots for the current setup/situation/examples.

And please give me your proper and detailed solution with your pricing and timeframe instead of; ok, let's do this.... Thanks!
