Hello Branny,
We've already locked in advertising partnerships for 3 websites, giving us a total of 55k unique visitors viewing our ad per day. We should ramp it up to around 100k a day right before launch. The pricing for these 3 partnerships is 1.35 BTC/month. We were able to achieve these rates (as well as surpassing our initial goal) through 'door to door' manual requests for webmasters to create long term advertising partnerships with Mintspare. Our marketing budget for our one month Beta launch (starting either January 27th or February 3rd) is 5-6 BTC.
As an additional note, I (Galfry) will be present during the Bitcoin Conference in Miami this weekend. I would be more than happy to discuss with any potential investors as well as provide private tours of the Mintspare office/warehouse. If you're just looking to say hi, I love saying hi too!
