Patrick's actual advice was: "Here’s what I’d tell a contract designer hired to re-do the Tarsnap CSS and HTML [...] a visual redesign will probably cost Colin four to low five figures."

Then he supplemented this with: " let’s hypothetically assume it isn’t in the budget. In that case, we go to Themeforest and buy any SaaS template which isn’t totally hideous."

So don't complain that it looks identical to 100 generic free wordpress themes -- that was Patrick's point, and his actual advice was exactly what you call for: spending a day to come up with something.
