The most cost effective solution would be to purchase just one of their programs: CoffeeCup Responsive Site Designer, but there are companion programs available that allow for more customization and flexibility. Fully-functional trial versions are available and you can get quick help from their excellent software support and user forums during the trial period. Yeah, there's a learning curve, but all of their software is designed with relatively unsophisticated users in mind, which doesn't mean that hot-coders would scoff at using it.
