Database/directory

[Hossack]

I'm not sure if this is the correct forum to ask this question, sorry if it is in the wrong place.

I would like to add a directory to my site (which I'm building with vB 3.5). I'd like it to have a series of catergories that are searchable and be able to update it via a simple form (only available to update by admin though).

Is there such a hack in existance or would I need to have one specially coded for the purpose?

I realise this is a bit of a tall order as the closest thing I've found to what I am after is the way http://www.yell.com works, so I may be asking for the proverbial rocking horse doo daa. :surprised:

Thank you in advance,

Hossack
