    I need to setup a system to allow users to claim free trial.

    You need to implement a fraud detection system that does not allow the same user to claim twice.

    - Have users verify via paypal or CC when claim a free trial
    - Detect duplicate email automatically
    - Detect IP address that have already claimed a free trial
    - JS script

    Any of the above, or suggest way. Wish to keep budget for this task $50, therefore kindly advice to implement a simple system that is within budget.

    Thanks

    Hi. I can do this work for you. I have worked with paypal. That would probably be the hardest part. But I do know how to do the majority of what you are asking. I should be able to figure this out within 1 to 3 days.

    I am a hard worker and a perfectionist. I have been programming for the web since 1996. In other words, I am ready and willing and able to be your best choice.

    PM me.

    Thanks.

    Hello @bebe99,

    Hope you're doing well & have found someone good at programming.

    People are enough smart these days. You need to FIND good way for VPN. People can hide their original IP through VPN. Lots of platform allow to create free email Thus you must need to think about it.

    According to my suggestion, You have to make CC details compulsory. Don't make them optional.

    This is what I have thoughts after reading your requirement.

    Best Luck & Hopefully, it will helpful to you.

    CC verification / PayPal, aka, requiring money before a trial starts, is usually a negative thing.

    Your best bet is phone verification, an SMS or phone call to a unique phone number, along with the duplicate email check (Isn't this a given is already implemented?), IP check and specific computer check.

    If you're still looking for help here, send me a PM.
