I am very interested in both of your porposials

could you tell me the cost per either Mh/s or Gh/s

and contract terms
I offer both share based contracts, and hash rate rentals for 7 days at a time...
I sell contracts at a slight premium, but you can point shares at any pool you want.
Share contracts sell for 0.375 BTC per 10,000 shares submitted, and if your pool starts throwing high stale rates out, I will suspend your purchase to protect you.
You can also purchase up to 500,000 shares at one time.
Hash Rate contracts run for 7 days and run on 2 teirs.
1,500 MHash/s for 8.35 BTC - This works out to 0.795 BTC per day per 1 GHash/s
3,000 MHash/s for 16 BTC - This works out to 0.762 BTC per day per 1 GHash/s
