These are good motors, and you can surely fly with these....
But they are currently going out of stock.

I am also planning to build quad with 12x12 alum booms and 2 plates 5" x 5" plywood + 3" x 4 " (3 mm acrylic) for battery with Emax CF2822 motor with 25A esc.
 
I have referred below link for prop Vs thrust for Emax CF2822 motor

http://www.headsuphobby.com/Emax-CF2822-1300kv-Outrunner-Brushless-Motor-E-510.htm

Lipo Battery    Prop                    Thrust    Amps    Notes
3-Cell (11.1v)    GWS EP9050    30 oz.    17 amps*    Exceeds max. amps
3-Cell (11.1v)    GWS EP8040    24 oz.    12 amps    
3-Cell (11.1v)    APC 8 x 4E    25 oz.    14 amps    
3-Cell (11.1v)    GWS HD8060    22 oz    17 amps*    Exceeds max. amps
3-Cell (11.1v)    GWS EP7035    15 oz.    7 amps    
3-Cell (11.1v)    APC 7 x 6E    19 oz.    12 amps    

so with GWS 8040 24oz per motor * 4 = 96 oz = 2720 gm / 2 = 1360 gm (max quad weight)

Is this enough calculations I have done my quad adventure? Or am I missing something to consider?

Emax CF2822 available on banggood.com, Is it possible to get it from there?

Nothing seems wrong with your calculations.....
You can buy these motors from banggood , but you have to wait for around a month to get it delivered.
And also compare price with , LHS, these motors are dirt cheap here (550 Rs)
