Ajax categories

Hello there all!

I’m looking to create something like this:

http://www.dollartreeinfo.com/investors/news/releases/

We need to be able to quickly sort posts using dropdowns, and then load post from the selected category within the same page.

The two Ajax category plugins that are available now, don’t function the way we need them… They load the posts in the Archive.php page, as opposed to the custom template page we’ve created.

Does anyone know how / someone who can to do this? We would be happy to pay them fairly.

Kind regards,
Owen
