Script question - very important

Hello !
I would like to know if there is a script available for purchase. Which one would work on the basis of affiliation and marketing?
My point is that I could post tasks on the site for users to perform, and I could add points or money for completed tasks, which I could then pay them out? Or and possibly cryptocurrencies as an opportunity to withdraw money.

I mean something like this page? can and can also be better. I want to open my similar page, but I can’t find such a script anywhere?

Is there maybe something like that available?

You will require to hire a developer for a custom work.

How much can such a service cost? and where to find a programmer?

You can drop me an email via this link then I can provide some information. I may even be able to help you on this project if we can agree the details
