Looking for a script/page

Let’s say I want a donation page on my website that when you donate it will give you VIP ingame (aka a flag in a database).

Is there something like this?

PHP, pay me and I’ll write you one.

I am looking for released scripts.

yes there are, but most of them are private, and will not be released for free.

how much? I got interested.

You have to make a module to give them the flag. You either find a script (rare), pay someone to make it, or make it yourself.
