Create a Mobile Website

I want a mobile website designed for a local oven cleaning business that mirrors their existing website. The existing website theme is currently mobile responsive but the owner wants a more user friendly mobile version that does not run directly off his existing theme. The website is [login to view URL] and the owner would like his mobile site layout to look similar to, and function in the same way as the mobile version of [login to view URL] but mirroring the background and logo of his main website. He will need to be able to manage content and image changes on the mobile site himself in the future and currently has images and logo available to use on the new mobile site. This should be a straightforward job for anyone with the appropriate skills and experience and your quote should reflect the straightforward nature of the project. Please mention the area Berkhamsted in your reply. If you have any questions regarding this project, please contact me and I will be happy to give more detail. I have attached a screenshot of the mobile design desired, for your information.
