I think its a shame you have such a high minimum - I would have like to put in my little half a bitcoin or something but there is no way I can afford $1000+. Can't say I'm very keen on the blind auction method either. But I wish you the best of luck and hope to one day be a customer even if I can't be a backer. In the meantime I've just published an article about this on my news blog:

Thank you for the mention in your article!
We understand that a blind auction requires quite a bit of trust in our team, so we hope that our prior reputations are considered when evaluating our proposal. There are likely other users here who would like to bid less than 1000 USD - perhaps they can get in contact with you to create a small group bid? In a perfect world we would accept bids of any size, but we want to avoid having to calculate the results of thousands of micro-bids. We would prefer beginning B&C development as soon as we can if the auction is successful.
