Thanks
There is no way to to realistically estimate this. Everything depends on how "lucky" the pool gets. In Turbo mode on Slush Pool I'm seeing about 0.00000170 (plus or minus a couple) BTC per block found. Figure about 1/3 less for your setting. Today so far Slush Pool has found 5 blocks, a few days ago it found 13 in one day. My last daily reward was 0.00001433 BTC.
Profit margin will, of course, depend on your cost of electricity and to a lesser extent internet bandwidth.
And... you don't really need 2 full packages. One "Full Package" can run 2 (maybe more?) "standard" units.
Good Luck!
