I won't help!
What I can do is help you define your workflow, review your documents, propose ideas...
Usually when people come in here asking for help they have a lot in mind, but just a few things on paper. And since we can't read their minds, the users demand more info on your project, anything visual or interactive to help them understand what the project is up to.
Of course, having previous experience, released games or prototypes, a blog, or anything related to games helps a lot when convincing people that yes, this project will be a kick ass thing and everybody should be working together.
For me, the best thing you should do now is develop a GDD (Game Design Document), and organize all the ideas you want to put in the game, in a very detailed way. Write the avaliable item, what does what, how many characters, write the story, maybe a few of the dialogues... Design a sketch of the interface, a flowchart of every screen... And then proceed to actually making the game.
And since you stated this is a free game, when you have the GDD, post it in here. Don't waste your time hiding your thoughts, because it will only make people ignore your project. Show it to us!
If it's truly awesome as you say it is (and I'm not using any sarcasm here), people will gather up!
Also, posting Filezilla screenshots to prove that you have a few .exes won't work. Let us play!
You said it is a free game, so there's no need to hide your contents! Also, people in here are used to test shitty prototypes, with bad graphics. And a lot of them evolved into beautiful games. Of course there will be trollers, eventually, but just ignore it and don't let it get to you.
Anyway, I can help you organize your thoughts and create a consistent GDD. With it you'll even be able to precise how many people will be needed to make the game, and I'm pretty sure everybody will be pleased to read it and feel more inclined to help in anyway they can.
So, what do you say?
