Right place, wrong expectations of interest. Young arrangers might be scared away by the lack of adequate details in your first post, while veteran remixers might shy away due to the curious absence of previous work being presented as examples. What does "get the brass together to play it" mean, exactly? Real brass, or brass samples? If the former, how do you plan to record it? If the latter, which samples would you be using?
That aside, you'd no doubt be better served perusing the WiP forums for promising up-and-comers and PMing them details.
