Help setup 300G acrylic

[colourfuldog]

I am in a process of opening a beautiful hair salon in Richmond I wanted to showcase a reef tank in the space.. So I whent to king ed where I rememberd seeing a custom acrylic tank in their barn...was still there so I then GOT IT!!
It's a 300 gallon thank and I currently have had my 80 gallon running for about three years now I've never had a sump I had mechanical filteration in the past but now running none for about a year. I'd like to have the coralife pro running on the new tank due to it's low profile good looks..
Basically I need you guys out there to help me create a grocery list to set this monster up in November...
How and what should I set up???
I have to mention I don't have much funds left.. I still need to open a hair salon not a aquatic store so lets keep costs in mind
any feedback helps. Thanks!!
