565783 Simple Software Website with cart Copy template etc

We are shortly releasing a new piece of software and require a website to accompany it. The website will only sell this peice of software and some other versions of it. We have selected a template that we like that can be copied and then customised. The site must use either Wordpress or Joomla, Wordpress preferred. The site must be simple and is targeted and non technical people. It must have a shopping cart and will use paypal too. There will only be one product to start with, but it must be easy to add products in future. This site must be search engine compatible and be SEO optimized, must be compatible with social network buttons too, i.e facebook like etc. The site and concept is very simple. Please message me and indicate if you are able to create the logo/brand too. Thanks for your time.
