$520 is way too much. Also, while Bicycle Rev are a good source of parts, they don't have a great rep on mechanicals.
I've been quoted $240 from another bike store for a build using supplied parts. I decided that I was better off spending that money on some tools and a stand so I could do it myself.
Also that frame doesn't look too bad. Does it need a paint? Or did you just want a different colour?
