Modification of existing EA

Dear  programmers

 I had an EA created that works very well, however i need some modifications. Now the EA works only with initial trades set as stop orders.  These modifications will be following:

When I attach the EA to the chart, there should be buy/sell button and text line where I can edit the comment and magic number and volume to be opened. By hitting the button, script will open a trade according to pre-set volume and comment and magic number at market price, this trade 1 will have only TP set to fix amount of pips.  EA will then automaticaly set counter sell stop if buy entered first or buy stop if entered sell entered first at market price. This stop order for trade 2 will be 30 pips away from market order, and volume of this trade will be multiplied by coeficient that I modifiy  in the EA. 

If trade 1 hits TP, then trade 2 ( sell or buy stop ) will be deleted automaticaly.

If trade 2 is being hit, SL of trade 2 will be set as variable R times range between entry 1 and entry2 . TP of trade 2 will be se as coeficeint 3 times range between entry 1 and entry 2. there will be new stop order for trade 3 with volume ( volume of trade 1*coeficient minus volume of trade 2) . SL of trade 2 will be set as coeficient2 times range between entry 1 and entry2. TP of trade 2 will be se as coeficeint 3 times range between entry 1 and entry 2. 

Example:

Entry long via script at market price 1.3000 with TP at 1,3030 volume 1 with comment xyz-1, EA will set automatically sell stop order at price 1.2970 with comment xyz-2 and volume 1* koeficient. Then I will manually edit the TP and SL level of trade 1 and trade 2, after that, There be will automatically set buy stop order 3 at price of entry of trade number 1, that ist 1.3000 with TP and SL levels of trade 1 and volume of trade 2*coeficient . If trade 3 gets filled, then there will be automaticaly set sell stop order 4, with SL and TP level of trade 2 and volume of 3* koeficient. etc

Do you think you can do this job for me?

Thanks,
