Yes, I'm looking for something they could input different info from their profile if they wanted (company name instead of forum nick, etc.). And opt into (since 99.9% of my users would not want to be listed).

Since this would be for commercial sites, it wouldn't need to be freeware.

I'd need to be able to specify some default fields, plus the member could add additional info.
Need to be able to locate worldwide, not just US (ie: not only via zip, a clickable map would be great for the initial narrowing).
Then the person searching could click on the fields important to them, provide a maximum distance, etc., and get a ranked result.
A "map this" link for each result would be great.

Imagine you run a site for any professional field (programmers, accountants, repair, etc.). Interested participants could enter their info, click on their areas of expertise, maybe add some marketing text. Then anyone looking to find a programmer, accountant, repair person, etc., near them could specify the expertise they need, how far they're willing to travel, where they're originating from, etc. Then they'd get a ranked list of the best matches and contact info (including an email link, homepage link, map, etc.)

I'd also like to be able to limit who could post on this (perhaps senior members only, perhaps paid subscribers, both, some other combo, etc.). And moderation would be a good option, as well (with notification that there are listings waiting for moderation). These would all allow the list to be kept on-target and high-quality.

I guess while I'm dreaming, I might as well add customizable metatags such as description and keywords, so we can have some degree of control over how these listings are googled.

Further thought: even better than a checkable list of interest areas, if they could be required to rank them (with zero being no interest or experience) it would help provide even more meaningful ranking results.

And ideally (for me anyway) the whole thing would run via a separate database (taking user info from vb db, but not making any changes to it).
