Could I ask for help with a phpBB forum coding thing, please?

Howdy! Would YOU have phpBB coding experience, maybe?

If you do, please, could you read the rest of this post, I’m asking for advice with something related to phpBB extension development

You see, there’s a phpBB forum I’m helping with (I repaired a crashed admin area, upgraded it from an obsolete unmaintained version to a still-maintained version), that is having yet more needs that, this time, I can’t provide for.

Long story short, even if, I know, that’s kinda weird, that forum needs the possibility to enforce a limit of “x” posts, per user, per day, per subforum. Post throttling, if you will. Trying to post more than “x” posts (both replies inside a thread, and new topics, both count towards the total) in the same subforum ends up in a rejection message.

And, regrettably, no such extension exists for phpBB nowadays, not for the two current versions of the phpBB software, 3.1 and 3.2.

I asked around, and while I would have been ready to give 50 bucks for a coder, to help friends, trusting I’ll be repaid in beers over the years, I’m asked in the 300USD for the job   And that, seriously, no way.
I replied “maybe let’s give up on cute admin panel configuration pages, hard coding things inside the extension’s code files or database tables, and the admins will have to use an editor like notepad++ or phpMyAdmin?” to which there was a reply, along the lines of “it would hardly make a difference”

Pardon me to ask, but if you have knowledge in phpBB coding, would you know if such a price is normal, or it’s just taking advantage of the customer’s lack of skill+choice?
And, in case it would actually be easy to code such an extension, couldn’t I ask you to write it, maybe? The 50 bucks would be yours with pleasure… Unless that really is a super complicated task, and then let’s just give up ^^;;
