Master and slaves account MT4

Hi guys, I'm looking for a script to implement to my meta trader 4 where I can do the following things:

I will have few master accounts where the script will copy the signal from, and it will copy the signal to the slaves account, I will have many because I do provide a copy trading service.

This has to be working on local, so I will have my clients passwords and ID, so my clients won't need to leave their pc open or to get a VPS server.

A important thing is that I need a lot split script as well.

This is an example, if my account is 1000 dollars, and i open a position for 0.10 lots, and I will have 3 accounts, one fore 500, one for 5000 and one for 2500 automatically the script has to calculate that the new position for 500 has to be 0.05 lots (because it has half money then my account) then for the one for 2500 has to open the same position I opened in my account but with 0.25 lots and finally for the account of 5000 it has to be 0.50 lots.

This has to be automatic and in proportion of the account size, for demonstration purposes i used easy numbers, but they of course might be different.

I need this script asap, so if you have something already built is even better, but as you can see my budget is limited, but if it has even extra features I can pay little extra.

Thanks!
