Logo design for a planned community

A friend of mine needs a logo for a community development he is building. I would like to look at about a half dozen loose ideas from which we will choose three to refine for presentation. I expect the final choice to be made on the first round of presentations. No applications of the logo (business card, etc.) will be needed. Final logo will need to be delivered electronically in a variety of formats, most importantly a clean vector file. The artist should expect to get pretty specific and prompt feedback as we are aiming to fasttrack this project. While we certainly expect this work to be exceptional, we do not want it to be posted on the web as a sample of your work...you may e-mail it directly to potential clients or include it in personal portfolios, but we don't want it on a website. Because this work will be used mainly for an entry sign, it needs to be a pretty clean, bold mark. A detailed work order will follow once the project has been awarded.
