Hey Spencer,
Skimmer looks great. Do make sure you're able to get it in and out of your sump. I had a similar problem and had to have Dave build me a second stand cause I couldn't get the skimmer in or out.
Also you'll want to make sure that Rubbermaid bin is food grade. Especially being black it may leech contaminates into your water. Do some reasearch on Brute bins as they are food grade. You can pick them up from Home Depot.
