2. It's a pretty big claim that you're going to be able to sustain $1500/month for 3 months with 14x 5850's... Least that was the implication. 3 months is hard to predict difficulty jumps and BTC/USD valuations if the sole way of paying back investor(s) is through mined BTCs...
Good luck on your endeavor however!

I also have +1.6 ghash to the plus 5.6 ghash also the worst case scenario is seeing me a month down the road the difficulty is way to high to pay you back I would sell all the hardware and pay you back as the worst scenario I suppose unless all the cards explode in a fiery explosion its pretty much fail safe pay back.
