Text link advertising website

Hello

I am working on a portal which aims to collate information on text link advertising opportunities that can be found on the web. This is aimed at being a resource for those that aren't shy of spending a few hundred $$ per month.

The purpose behind the site - as well as it being a helpful resource to us and its visitors - is to hopefully draw attention to text link advertising opportunities that exist on a number of our own sites.

My questions are:

1) does this sound like a good idea?
2) is it something you would use yourself?
3) are you aware of any similar sites out there?
4) what would you look for in such a site?

My thoughts so far are:

1) maybe
2) ?
3) I haven't yet come across any
4) obviously it would be useful to present things like rates, number of text links that you get for that rate, targeted categories, Google PR, Alexa ranking, etc.

I've drafted something very quickly at http://www.dedicate.co.uk/textlinkadvertising which will hopefully give a fuller insight into what I'm trying to put together.

Most of the links don't work (that's deliberate) but you can click on the 'Travel' category, and from there you can click on 'Aardvark Travel'. Each featured site will have a page like this, with links that enable users to get a fuller insight into the site's popularity and size.

Any comments on this as a first idea would be appreciated. It's very much work in progress so I expect plenty of criticism at this early stage.

Thanks all...
