use any mining calculator to calculate your earnings:
there is one : http://www.coinwarz.com/calculators/zcash-mining-calculator
as for the hardware ...
there is my another build with price and some basic hardware info i posted in another topic its 250 $ over of your 2000$ budget with 7 gpu , but with 6 gpu you will be in that 2000$ budget
i can post a link to those hardwares if you want me to do
i would not suggest to build a 7 card setup , its not that easy to make a 7 gpu setup stable .
Hash Rate: 210MH/s (ETH) & 980H/s (Zcash)
UPDATE AS OF 11/25/2016
