I'm also interested with this offer, but seems the OP has been very busy now and he has so many clients lol! we have the same question to him, is it trial or need to pay a monthly subscription and to whom we need to pay.
I already contact with him on what's app from his website. And bought a Netflix premium for 2.5$. it's a 4screen account. 1st 2 account was showing incorrect password but both time he gave replaced account in a minute and I'm using the 3rd now. Let's see how many days it goes. Though he gave me 15days replacement warranty.
If you want to contact him I will suggest you to contact though what's app to get his reply fast. Let me know if you need to know anything else.
Im very interested with this offer but seems the OP is very busy now watching his favorite series on netflix, I hope he will give us a proper and clear information about his offer.
