canadasarctic would be a great one for developing as a news/blog site covering soverignty issues.
As for selling, you might want to contact some tour operators than do business in the North. If you can find an enduser then I'd set a price around low xxx
Reseller/mini-developer low to mid xx
If you can, develop this yourself and value could increase over time as the arctic continues to become more accessible to tourism and industry.
