Robot/EA [MQL5] f. daytraiding/scalping

I'm looking for a freelancer who's able to program the following EA/robot for MQL5:

The EA uses trailing stop loss. As trade turns negative, new trades are being automatically executed at fixed levels. 

ENTRY:

- first entry executed manually by trader

- trailing stop loss is used as trade goes positive (see "EXIT") 

- as trade turns negative, a 2nd trade has to be automatically created at 300 pips difference at same LOT size;

- as negative trend continues, a 3rd trade will be executed at 350 pips difference of 2nd trade with doubled LOT size

- as negative trend continues, a 4th trade will be executed at 400 pips difference of 3rd trade with doubled LOT size

- as negative trend continues, a 5th trade will be executed at 450 pips difference of 4th trade with doubled LOT size

- etc. 

EXIT: 

- trailing stop loss is enabled at 140 pips with 20 pips difference

EXAMPLES:

- trader manually opens buy trade of 0.05 LOT AUDUSD at 0.7800 

- as trade goes positive: trailing stop loss is set by EA at 0.7814 (at 140 pips with 20 pips difference) --> sell is being executed at 0.7812 or better

- as trade goes negative: EA opens 2nd buy trade of 0.05 LOT AUDUSD at 0.7770 (at 300 pips difference to initial trade)

- as trade continues negative: EA opens 3rd buy trade of 0.10 LOT AUDUSD at 0.7735 (at 350 pips difference to 2nd trade)

- as trade continues negative: EA opens 4th buy trade of 0.20 LOT AUDUSD at 0.7695 (at 400 pips difference to 3rd trade) 

- as trade continues negative: EA opens 5th buy trade of 0.40 LOT AUDUSD at 0.7650 (at 450 pips difference to 4th trade) 

- etc.

- as (accumulated) trade turns positive, trailing stop loss is enabled at 140 pips with 20 pips difference and position closed

UPDATE:

Reply to angevoyageur: Yes, I am aware that this strategy will result in having only one position open at the same time...
