Here is something I do when I need design inspiration.
Say I have a fine dining restaurant site. I will note the category and first do a theme Forrest search to see if anything tickles my interest. Then I will do a google search for specific cities in this category and find sites that may have a section or footer or whatever else and take screen shots. Once I have about 3-6 shots of a rough direction, I can then go over the hero shot ideas, logo, and menu hierarchy and begin to put the first remnants of a homepage together
