Take a home-made website and turn it into a professional looking site

Take www.estudiainglesenuk.com and create a more professional looking website. No functionalilty is needed nor any additional content.

Brand - keep the colours and the syle of the logo / header
Layout - I imagine an intro page - with static links into 3 detailed pages. Detailed pages can be more text heavy, but main page should be inviting and professional.
Content - All content exists already, should require no significant changes to the content. I can provide reworked wording if shorter front page wording is required.
Market - The page is for Colombians looking to come to the UK to learn English. Typically in the 20-30 age range post degree.
Deliverables - HTML and CSS for 4 pages for the site.
Timescales - Ideally within a week from agreement, but 2 weeks could be ok.
