I completely agree with Clark on this one. Our small press began with a lot of great ideas (IMHO), but sitting down and making those thoughts materialize is really where the rubber hits the road, so to speak. It takes a lot of time and dedication to bring something from the concept stage to its first rough draft form. Working to make your ideas tangible (i.e., in manuscript form) will show publishers that you are serious about working -- as well as creative. Best of luck! 
Cheers!
