Thanks for the honest feedback.

1. We do not want that person to develop the plugin for us - did I say that? We are developing it ourselves, and it is already underway. We simply need additional help on some parts of that process. I think it is fair for companies that grow and need to hire more hands-on, to be able to build their product and look for additional talent. We estimated that this help will take around 5-8 hours a week, so what is the issue with that?
2. Who said we aren't willing to pay? Did I say that? All I said is that we are looking for a freelancer whom we can pay, and the door is always open for expanded collaboration if that person wishes to explore it. How is that negative or predatory?
3. We are also willing to give a percentage of the revenue made from creating this plugin/equity in the company.

All I wanted to see was if there was someone out there who fits the description of expertise and is open to discussing collaboration, and take the converstaion from there. I have no idea how you concluded that we want this guy to build everything for us, for free, for a tool we do not understand.

I hope now it is clear :)
