a comparison site to compare gas and electricity prices for businesses

I need to develop a website which is a energy comparison site. It will have a main landing page, where customers can input there details in order to get a energy comparison done. It needs to have a home page, about us and contact us page, with a blog. Bare in mind the website will be expanding as time goes on and the website grows. We will be offering advice pages and adding more products in the near future to the website. I need the pages to be ready where I can simply add articles or content myself. You will need to develop design layout for the website as well. The layout must be simple, eye catching and relevant to the industry with the right colour cordination making it look professional, so past experience of designing websites is of paramount importance. I will be writing the articles, doing logos and all the rest myself, you will not need to do this. You will mainly be building structure of the website, which includes the theme,design and give me all the tools and logins to ensure I can further edit and add articles on to the website. You are mainly building template structure of the website, so I can go ahead and add everything myself this has to be SEO friendly, which is of paramount importance I need the design to be eye catching professional for the site which will be used on all pages, I am willing to work hands on this project and be assisting at all times. The basic structure needs to be completed within agreed amount of days so I can launch, I will go through templates and websites I would like it too look like. I need it to be simple with quick loading times and needs to have ease of accessibility.
