Good, but you shouldn't need quite that much if you can diy some quantum boards. A bunch of us have used Alibaba to order LED boards and drivers directly from china.
I got over 1200w at the wall quality samsung 561 LED boards and drivers and built them frames for around $1200 doing this, I have 16x 120w boards and 4x 320w drivers. I drive mine at like 80% for efficiency. 1000-1200w of GOOD led should do your space fine if you space them right.
Check out this site to see some built examples that use the same LEDs. The boards you can get from china are nearly identical for like half the price.

You want samsung 561 or 301 diodes if you do boards. The 561s are a bit older but considerably cheaper. The 301s are a little better pretty much all around if you want to spend more to get the best. 561s are still great though.
This forum has a great sub forums for lighting. I highly suggest you dig deep into it and sites like LED gardener and see how deep down the LED diy rabbit hole you want to go.
