Are you sure your prices are correct? I know it's a top-notch quality outreach but still - 1K a link?
I mean, I have a website that surpass your criteria, has more than 100K monthly traffic, and still the best offer I got for a paid placement was $250 (which happened only once, other times it's between $50-$200).
No offense in any means, wish you good luck with this and for sure quality will be outstanding. Just the pricing makes no sense to me, especially knowing the prices of your competitors. Or maybe I am just missing something here?
