I need a professional web design

We want to redesign our website www.3dmxconsulting.co.uk and have the wireframes ready for all the pages. Main pages will be Home, Portfolio, Services and Blog.

Iam looking for a designer who can create the designs and create HTML5 pages. We are looking for high standard work with validated code, fast response times , multi browser and multi device support. The layouts are simple but we are looking for good color schemes and presentation.

I also need some infographics ( professional/ technical- not funny ) created to be used for the homepage slideshow . Details of information/ images to be shown in each slide will be clearly given. If you have experience , please send samples - will be great if one person can do both tasks.

Budget is negotiable for the right candidate.

Note : We are not looking for Wordpress Implementation.
Just front end development.
