I want to build a real estate listings web site, using google maps API. The site is to be used for residential properties that are for rent and for sale. Similar site that I would like to clone are [url removed, login to view], [url removed, login to view], and cityscribs.com. Data Source 1. The property listings can be entered manually by the advertisers. One or more listings can be entered at a time. 2. Spiders that can read meta data (property listings) from other real estate sites. 3. Manually entered by system admin. The website will need to support the following: User Types 1. Users looking for properties. Be able to save interested properties. 2. Advertisers listing porperties for sale or for rent. Should also have functionalities as User Type #1. User Account Management - Please look at [url removed, login to view] for the types of user account management functionalities I'm looking for. This is just an example, I willing to listen for other suggestions as how to implement these functionalities. User Search Criteria - Please note the followin is intended only as an example of the required search criteria but, not as a design layout. search (city, state, zip, MLS, WebID) (parse string) state city Type (condos, townhouse, single family) Price $$$ to $$$ Bedrooms Baths xFor Rent xFor Sale (Search) (Advanced Search) Advanced Search - pool - garage - size (applies to condos) - search properties near a specific school district - search properties near specific military base - search properties Filters (on/off) - Metro stops locations - School locations (elementary, middle, high school) - military base locations - shopping centers Admintration Tools - provide necessary tools to adminster site, update content on site, update database, track performance and traffic. I do not care how the script is derived. Meaning, whether you clone this from a similar site, developed it from beginning or a combination of both. The important thing is that the code needs to be well structured/developed, efficient and can be easily modified and expanded. All IP for code and script will belong to me when completed. Thank you and look forward to your competitive bids !
