Donation through in-game

Hello, my name is Zeo Mause. I was wondering if there is any type of donation system that is right in-game and when you want to purchase such as amount of credits it will take you to the Paypal page. See, I am searching for a credit based donation system that isn’t Prometheus nor VXDonation. Maybe someone could help me out, this type of donation system would be great for many communities since it is strongly desired. I tried my best to get a script fixed on Scriptfodder but not much luck.

Here is an example of a credit based system:

I guess the best thing to do is go on scriptfodder and either buy one or start a job.
I doubt there are any of these for free on the internet.

Why not. Divinity has one. People of Gaming has one. These type of donation systems are great.

There are so many more advantages of using the web.
Plus, you can just use a DHTML panel.
