Looking for some advice

Hi, I've had prebuilt drones in the past and am just starting to take the leap into building my own hexcopter. I want it to be a heavy lifter as I will be strapping a paintball marker underneath for use at special event games.
To save a bit of money and time I grabbed a part built one off ebay, but now i'm regretting it as im not 100% sure what the actual specs of the parts are, and so adding more parts to finish it off is getting complicated! I know I need batteries, but not sure which will do the job to give me around a 30min flight time. I know i'll need a radio controller, but not sure which ones will work best with this setup. Also are their any other items I should be looking to buy or upgrade?
Here's what i've got so far.
Turnigy HAL Hexcopter Frame

6 x 35 Prodrive 35-30 1100Kv Multicopter optimized Brushless Motors

6 x ProFlight UK 30A Multicopter Optimized ESC's.

6 x Glass Fibre Props

KK LCD Flight Control Board

Power Distribution Board

Since no one else has jumped in....

30 minutes flight time is very optimistic with just a Hex, no payload.
What's the weight of you paintball system?
Recoil from firing is going to mess up your flight control!

First with 1100kv motors will bevery difficult to be a heavy lifter. You need lower KV motors that have more torque. Second 30 minutes very, very difficult. You will need a hex converted to 680+ to get 12+ props. BUt 1100 KV will not be able to move those props. So you need to re-design your multicopter
