EA for auto copying signal from Telegram channel to MT4

I’m looking for developer that could help me to develop an expert advisor (EA) and Telegram Signal Auto copier to be developed for MT4

Below are the basic functions needed:

1. Read and copy trading signal messages posted in specific telegram channels with different format to MT4. The EA must be able to ready different format e.g TP or Take Profit.... -> define String to find Take profit) Order parameter like Pair, Buy/Sell, TP, SL, entry price/immediate execution should be respected according to the signal.

2. Copy all the signals included Entry Price, Stop Loss, take profit 1, take profit 2 and take profit 3 and trades into ea and run.

3. Ability to add more than one Telegram channel and should be selectable in EA or changed/added in source code.

4. Read customized messages on telegram

• Customizable to signal provider format e.g BUY NOW, BUY @, BUY AGAIN etc –
• Accept close commands in signal formats (Customizable): e.g  For example e.g. Close Now, Close at Entry, Close half, TP HIT (or HITTED) etc (usually in reply mode)

5. If a trade has multiple TP levels like TP1, TP2 and TP3, the EA would need to be able to partially close a % of the trade at each TP level.

6. Lot size customizable (there should be setting for lot size )

7. Trailing stop: any order that opened by the EA already hit 50 pips, the EA will move the Stop Loss to entry price. 

8. Source code needed

9. Licensing system: based on account number and expiry date

I need the demo version of the EA in ex4 file. I need all the parameter setting for each function.
