Let's say I want to set up websites for offline clients (for one niche) as quickly as possible using WordPress. Some basic good-looking, functional sites (5-8 pages) are enough. What's the right way to do it? I might want to do certain things in one shot - like backing up all the sites, installing plugins common to all client sites, changing custom post types, upgrades, etc.
I'm thinking of a platform like HappyTables.com.
