We bought a video script ( phpvibe exactly ) in order to offer videos to the users and add subscription plans. This script doesn't come with a subscription option, and what we need is you to create a payment option for it with paygol.com, payza, and fortumo. The users must be able only to watch videos after they pay, and we need to alter the mysql database of the script in order to specify an expiry date for the users. More will be discussed privately. Since this is the 1st project we do like this, if the payment gateway is a success you'll be our dedicated freelancer and we'll have a long-term relationship because we need more modifications for this script.
