Need MT4 indicator protected in DLL with Licence key Authorization

I have an MT4 indicator that I need protected in a DLL file. I have had several indicators protected in the past, some were great but many got cracked. I need very strong protection for this simple indicator. I need the indicator to only work if it is authorized from my server so each user should have his own unique MD5 key and there should be a option for me to limit the amount of MT4 accounts the user can use it on. Once again I say, the protection of this DLL file has to be strong or the authorizations mechanism will be broken! My budget for this is as is so please consider that before bidding.
