How to create a directory: Help needed

[Gerry]

I want to create a directory for a new site/project.

As an example, lets say it is art related.

The site would allow people to post works of art for sale by type, locations, etc.

The directory would be auto updating:

Impressionism (3)
Lithographs (7)
Modern (11)
Prints (6)

and so on.


Now, this would be a one time fee for people (say one buck) to post on the site.

But, when they post on my site there is a feed to Twitter (possibly other social networking sites) updating the listing.



While they post, the information is indexed for searches.



Say I want to search for George Bellows

The results would pop up for that name, who posted, and where the item is located.



I would also like to construct another directory for Art Brokers/Dealers.

This would be say a 5 or 10 buck fee.

The gallery, broker, dealers would

Art Brokers/Dealers.

And so on.


The biggest factor is this would need to be a searchable index.

For example, I want to search for

George Bellows -

The search results would bring up works for sale, etc based on the data entered by the users.



If someone has a pretty good grasp on the ideas I am trying to convey and can post examples in a PM (preferably of their work) I would like to look and discuss further.

Thank you in advance.
