Customise and existing WP template

I need to create a landing page type small website for my startup. Need a cutting edge and bold looking visuals for the home page. Also need to create some graphic designs to explain, "How it works" and "what are we". I will give precise instructions on content but need input on artistic presentation and user journey. The design and visuals must be top class and cutting edge. I have purchased a WP template that can be used http://demo.pixelthrone.com/?t=moonlight&o=wp&ref=tf
