I have tried to get this idea off the ground but didn't find any partners. But don't be discouraged cause maybe I didn't try very hard lol.
Anyways the idea is to find handcrafted stuff/art/one of a kind things. Then, create a site where there is an auction in MZC. This could help generally anyone who is holding mazacoin cause there is actually something cool to buy with it. Most importantly it would help native tradespeople find some new customers from a pool of people that kinda already showed interest in their culture (by being interested in MZC!)
When I tried to get it going a really hard part was just explaining mzc to artists lol... but I am sure some are also computer nerds and think it was a cool way to sell art!
My opinion...
1) Create a high quality auction or sale site: easy.
2) Find artists / tradespeople who will make use of the site even before it gets any publicity: a little difficult
Where do you find them?
3) Popularize the site: extremely difficult
New auction or sale sites are a dime a dozen. Almost none of them last a year.
Effectively marketing art sites is very difficult.

Some examples of Native art sites
http://www.rivertradingpost.com/http://www.artnatam.com/https://www.nativeartsofamerica.com/http://www.nativeart.net/All of these sites rank very low on any measure of traffic. Some have some pretty severe technical flaws.
Maybe a more practical idea would be for somebody to make one high quality site then contact all of the Native art sites they can find and arrange a partnership. e.g. "We will post all of your art for sale on our site using our shopping cart system and will pay the artists with Mazacoin".
