Online License MT4

I want the license System to manage EA licenses. Able to login website or software where i can add and delete licenses for an EA. The EA will need the license as a parameter, only then with a valid  license it will be possible to trade. The license system will check if the license is valid.
it should work on mt4 and mt5

In the webpanel i want to control the max allowed lot size, and balance.

It should be possible to have an expiry date time, when the license will be not valid no more.

need following features :

Server protection (Licenses Management):

I can add / remove / edit clients remotely

I can stop (disable/enable) the license from server 

I can set a trial period for every client and product (demo account only)
