Website template using Silverstripe

I have a website using a Silverstripe template that I need changing from pink to yellow. Changes will involve editing JPG images and the website structure in HTML and CSS files. There may also be some additional web development required to change some pages within the current site. I would like to see examples of the websites you have worked on to confirm you are able to assist with this piece of work. I will provide you with the web address and log on details when I am confident you are able to complete the work.
