Interesting offer, but three items are not described:
1. Access to miner interface (how it will be done).
2. Do you ship miners to owners at their demand, and if so, what is the price of shipping to regular indications, like US, for example.
3. How is the fee collected (daily, weekly, biweekly, monthly)? I prefer to pay fee in $$, not by taking my mined bitcoin away from my account. If so, how is this done?

Pending this, i am potentially interested.
