sharepointpackages.com alternative templates / themes options

Hi,

I have recently come across a company who is providing pre-styled templates / themes for SharePoint 2013. 

Here is a link to their offering

They offer a platinum package that includes CSS styles, design packages, master pages, layouts, custom content management plus more. 

My question is....are there any other alternatives that one can think of that provide this same solution?

What are your thoughts on using this as a base starting point for an intranet site or internet site?

Thanks
