encode PHP files with Ioncube encoder 8.3 (PHP 5.5) lifetime for specified domain

I have 15 files which I want to encrypt with ioncube encoder. the version will be 5.5 so you gonna use ioncube encoder 8.3 . the files will be licensed to the domain (not ip) for lifetime. I will get the files and will wait 2 days if it is not expired I will pay you 5$ for this. the reason of waiting 2 days is , it is possible to use trial version of Ioncube encoder so I need to make sure.
