Need custom programming

I need a script (I think it's called) for Metatrader, that when caps lock is on + B = going short. Caps on + B again means getting out of the trade.
The same goes for 'long' with caps on + H. Caps on + H again means getting out of the trade.
Stopp loss is a predefined value in pips.
I'd like the total amount of pips in the last 4 hours in large font on the chart lower left. Font color should be adjustable/switchable.

Project is currently on scriptlance - search for 'script+ea+metatrader'

Thanks!
