I suggest using an engine that isn't so dated, firstly, for the Mansion/5days Mod. Perhaps Doom 3 or Half Life 2. The Deus Ex Engine isn't bad, it's just older.
And you really have no concepts or storylines posted for either, so I'm not sure that anyone at all will see anything to have interest in.
And I think you want a Game Designer / Project Leader, not a Producer. Or maybe I'm getting caught up in the wording, but a Producer is, I think, basically the liason between the Publishing Company and the Team that is making the game. Since both projects are modifications using other engines, unless you own licensed copies of those engines, it isn't likely you'll get published (unless you make one hell of a mod).
