I have 14 units of mining capacity currently available for leasing. Each unit is 250 mhash/sec and is zero variance. The lease rate depends on the terms, with more favorable rates for longer term leases. With leases there you receive zero variance payments daily. A one month lease is $120, two months is $220, three is $300, and additional months are $60/month all paid in advance. That's as low as $0.24 per mhash per month. Months are always considered 31 day periods. Compare that with the prevailing rates. If you rented 1 ghash from me for 4 months it would cost you a total of $1440 ($360 x 4), while others would charge 1760GBP, which is more than double.
Payments will be based on the rate determined here http://www.btcserv.net/bitcoin-calculator/
, which at the current difficulty level is 0.18232btc/day per unit leased. As a bonus to my first customers and because I have a bunch of bitcoins sitting doing nothing, I'll give you at least one week of earnings in advance upon receiving payment. So instead of receiving payments of .18232 BTC a day, I'll send you 1.27624 btc the first day (or more, haven't decided yet) and count that against your future earnings. In the end you'll get the same amount of coins as if you were paid daily, but this way you'll get them quicker and I won't have to make as many small payments.
I also have an option where you can own the mining equipment and I will operate it for you for a small fee. The cost to own the rig would be $220 per 250mhash unit, and it would represent a rig with Radeon 5830s, 1 GB ram, a flash drive, and a sempron 140. You own the equipment and at any time can shut it down and ask me to mail you the hardware (you pay shipping costs) or sell it for you and give you the proceeds. The computers are online now, and you get daily dividends. I operate them for you for $1.50/day in upkeep until it becomes unprofitable or you want to stop. If something breaks while you are paying upkeep I replace it for you at my expense. If there is downtime I cover it for you. You can buy individual units (250 mhashes), so you can own just one unit for $220, but in order to redeem for a full rig you would need at least two shares and to pay for shipping from the east coast of the USA.
I would prefer payment via some method with no chargebacks, so I will gladly accept bitcoin or Mt. Gox transfers when they reopen. If you have any questions please post or PM.
This isn't super relevant to the mining operation, but if you are worried about security, I also have an ebay business with nearly 10,000 feedback and monthly sales of around $30,000. You will have all my details to see that I am legit.
