Ecommerce for online pdf selling
I am interested to start ecommerce solution for selling pdf files online. I have lots of solutions pdf files ready for academic subjects.
My target audience would be Student.
Well, I am facing difficulties at startup about some fundamental regarding pdf files security. Where should I put my solution pdf files?
Someone told me to put it on website host server machine. But will be it secure to put all my files over there as I am going to use third party web hosting service?
Can you please recommend me any such data storage service exists which can store pdf at minimal rate/month and when someone purchase it, I will use that service to provide link to my user?
Thanks in advance,
