Your estimate of 30 Khash/sec for 2 cores is over estimated unless you are using a very highcost Intel Xeon.
They're Dual L5420's, but yes other CPUs can be looked into.
So, I pay you 2.56 LTC for 2 "cores" that will be available to me for a month, those CPU's will run 24/7.
So at the end of the "lease time" I get my part of the LTC (which will be more than the 2.56 LTC I paid you).
I am interested, if you clearify it a bit to me
Yes, the 2 cores will be dedicated to you and you can max them out 24/7 and mine any coin you want.
No, I cannot guarantee you that your income at the end of the month will be more than 2.56 LTC, the difficulty could double or increase drastically which would make the number of coins mined with this naturally lesser.

This. OP is essentially selling $17 for $10. Either OP is generous and foolish or OP believes the trade is a good one. $0 for $10 is a very good trade for one party ...
It's not for certain its going to be $17 at the end of the month, it can be more, it can be much lesser, what I posted earlier was just a rough calculation, everything depends on which coin you're mining and how much that coin is worth and ofcourse the changes in difficulty and exchange rates.
Lets put it this way, The market fluctuates too much for my liking hence I'm offering this to those who like to "play".
I'll see, but still count me as interested...
You can basically mine any coin, not just LTC, it can be TRC/PPC/BTE/BTC etc
So the profit / loss depends on which coin you mine
