Condo Assoc. looking for building website

My condominium complex is looking to have a website built for the building. I am looking for a simple 3-5 page site. Here is a basic idea of what will be on each page: Homepage: The homepage will include a photo and an area where I will be able to post building updates. It's be nice to have a little area off to one side with a random little weather gadget or something? Links page: This page would be a tool for residents as we will put links on it that pertain to the building (management company, local plumbers/electricians,etc. Forum page: The complicated part of the site lies in our wanting for a 'craigslist-like" posting page. I will need to be able to manage login IDs & passwords for everyone in the building. Unit owners will then be able to login to the forum page and post a posting in one of a number of categories that we initially set up. I must be able to remove certain posts. I might be forgetting a page or two, but the basic idea is laid out. The bulk of the project lies in the forum/posting page.
