Re build Website with new dynmaic theme.

We are looking for a motivated freelancer to transfer our website to a new modern dynamic theme which is fluid to use on mobile making it easy for people to shop. We are happy to choose from templates and then customize the design. But the templates must be workable with the current functionality of our site. We would like the graphics and colours to be the same but also merge in some high definition product photos to enhance it all. The website must display high quality images in a modern sleek (but fun) design. The freelancer we are looking for has an eye for design to suggest ideas and give example of areas we can improve with the graphic design of the website. There are a few changes we would like to make to how the website works. We would also like to simplify it and add a user product rating system. The right freelancer will be happy to spend some time getting to understand the site and then work to improve it within the budget you set with your quote. You will be apt in coding and confident working alone and ad hoc with changes that need making along the way. Time is of the essence. We want it done asap. No messing around.
