Motown-style Brass samples? Dare I hope for ... freeware?

Looking for really dry and gritty Motown brass - doing a cover of "Mr Big Stuff  - Jean knight". No real budget for buying samples... anyone know of some good stuff out there?

Hev not listened to these but this is a link from a hip-hop production forum: http://www.nois3.com/2011/06/brass-horns.html most of the sample packs are assembled by individuals so i don't know the original source

LJB, are you going to do single keyboard chord brass sound or multiple part horns arrangement ? 

If it's the later.. may I recommend Garritan Jazz Band.. the more I work with it, the more I like it. For example, for trumpet alone, you have 5 different trumpets, and for each trumpet you have a open, straight, cup, etc..(further 6 more types of sound). 3 different kind of saxes for each range, etc.. really flexible way of assembling the wind section. But you have to do single line arrangement for each of the instrument.
