I want a data trading website. On one side it will be collecting, crosschecking and storing data. And on another side it will be selling data to buyers.
So it must have user accounts module, with user permissions management based on their membership status. And on the data collection side it must have extensive data crosschecking functions.
For instance, any new piece of information submitted by an informant must be crosschecked against existing information in the database that has been provided by others and stored earlier.
Information will be submitted by users. Information will be about people, and assets. The trading will be based on barter and money. Barter trading will be such that a user can request and receive on set of information about a person or an asset after submitting say five sets of information.
In simple language say you tell me about 5 persons you know, and I'll tel you about one person you are searching for.
And for money paying users there should be options for one-off purchase, or periodic subscription which allows them to download or access a certain number of reports. All purchases must be accessible of their account. It means they must be logged in to view, or submit anything.
The external website must have a sleek fluid (light) feel of a modern website, if you know what I mean. Like those webpages made with Ajax.
The website must also be SEO-friendly. It must have SEO-friendly URL with names of any person or any asset that we have information on so that when someone Googles the name our website will appear in the SERP's
How much could such a website cost, how long it can take to make?
