Clarification on policy regarding COI and whatever paid editing policy says today for this specific instance 

With the recent talk, in many different places, about editing for pay and all that, I would like some clarification on what I need to do and where I need to do this- I would like to work on getting Fulton, Missouri to at least GA status and to create and get to at least GA status Downtown Fulton Historic District; however I have a COI in that I will be working with the merchant's association, my business is a member of the relevant Chamber of Commerce, and I have a financial stake in a website that will benefit from increased interest in Fulton, Missouri, though not DIRECTLY from a Wikipedia article as my website will NOT EVER be used in any manner on any article. All interested parties that I have spoken to think having Wikipedia articles that are informative and can be linked to from their organizations would be a great asset; what exactly should I do first, and what can I tell those that want to join Wikipedia and edit these articles as far as where to "register" their COI and how to do so without being assaulted with "You're doing this because you have a vested financial stake" or "You're getting paid! BLOCK!".
