Add-on I need a custom addon coded.

I want a Q&A section node that does the following:

1. When a user wants to ask a question, he must pay a certain point to be able to ask a question. This section can be accessed by everyone but the content here is only available to the following:
User - to the thread he created and paid with.
Staff - everything is visible.

2. When the user has selected his answer, he must finalize the question, and the point should be forwarded to the person who answered his question.

I also have a lot more code projects. Just want to be connected to the best developer/coder.
I've sent messages. If you PM me, please do include your portfolio so I would see your past work. That will definitely increase the speed of things.

Thank you very much.
