I need a professional, modern, and responsive website design (based on wireframe)

Industry: Business
Kind of design: Custom website
Num. of web pages: 6
Ideas for the visual style: modern, clean, parallax, image and typography led design. clear and simple design that uses gold, white, black (representing "black gold", oil, etc)
Things to avoid: I have an existing wireframe that needs to be adhered to
Website information: The design is for an oil/petrochemical company that supplies both petrochemical products, and related financial services
Urls to draw inspiration from: http://almasaoodoilgas.com/ | https://www.rackspace.com/
Extra notes: I am looking for a London-based web designer who is able to come to our studio (if possible) in North London for a couple days per week if needed to complete this.

I have existing wireframes that need to be designed into a modern, clean website. More of a briefing will be given to the chosen supplier/designer.

Design will only need to be done, as we are an agency who have developers available.

Wireframes are simple and clear to follow, and will be shared with the chosen designer.
