Well, you are a big name on NG, and we're just--well, we're just dudes, so you can post however you like.
But, it doesn't make any sense. From what I've gathered, someone pms you and you pm them the info, which I assume is form letter-esque. It would've been easier to just post the information which would've increased exposure to more writers (also, details like which other forums you've posted this in would be nice; I hope you didn't post in General or Fanfiction.net, for example). Also, it would help to have some sort of process, at least. Something like:
I am looking for a writer to (insert job description here) for a (insert genre here) (insert medium here). The project will be headed by me and includes (insert other collaborators here). The project is will be (1-2 sentences about what it is). I have experience as (insert jobs/work here) and can offer (insert compensation here [you said revenue, but writers' credit is enough]). Please PM me if you are interested. Please include contact information (such as e-mail, or NG PMs), previous experience (writing work for other projects, writing contests etc.). I hope to hear from you soon. Thanks a ton, mi amigos--Yeehaw! (you don't need to include that last part).
Something like this will not just be easier for both of us; it should smooth out the application pool.
Also, I don't understand the reticence. Your idea can't be so secretive that you will divulge the information to any person who pms you, and I doubt it is so complex that it can't be summarized or described. You might as well make it public. And to agree with Deathcon: I sincerely hope you select someone from the Writing Forum.
