Description of requirements/features: I am looking for a company to make a new website that uses wordpress for us based on the design of our current website www.unexpectedplaces.co.uk.

We need to change our website as it is currently not mobile/tablet responsive and we are unable to edit anything apart from the text. We want to keep the current url. We want to keep the colours and the layout/ font of the front page and 'The Team' page. We like the current design, but need a new website to have improved functionality. When created I am able to edit copy, add pages and change simple elements. We are looking for someone to complete the design aspects only.
