I need a person to write webpages about gallstones for our private medical practice

Num. of words: 8000-9000 (400-500 per article x 18 articles)
Website url: www.gastrolondon.co.uk
Industry: Healthcare
Tone: Formal/Professional
Outline & Structure: We are looking for 18 high-quality pages, ALL OF 400 TO 500 WORDS, to be researched written to form a section about gallstones on our private practice website. The pages are to going to be put on the site in a tier-structure (so higher tier pages need to be written to link in to lower tier pages, as explained below)

The pages are to be structured as follows:
1) Gallstones introduction (top-tier page) - this will primarily aim to link in to the middle tier pages
2) Causes, symptoms, Investigations, Treatments and self-help will all be middle tier (tier 2) pages. In most cases, there will be lower tier (tier 3) pages underneath them and the primary goal of these pages will be to link into these pages (e.g. by having a short paragraph about a certain treatment option which will then link to a more detailed article)

We have a document with the 18 pages and keywords we wish to target which is attached.

We would like the job done in two stages:
Attached are listed the 18 pages which we wish to be written, as well as which keywords we wish to be included on the page. In the first step, please give a short outline (e.g. a short bullet point summary) of what information you think should be included on each page. For some of the pages , we have already given a bit of an idea as to what the page should include.

Once you have made the outlines, it will then be reviewed by a consultant who will feed back and either approve or modify them. We will then ask you to write the pages on the basis of the agreed outlines. Of course, we expect the content to be totally unique.

The aim is to attract potential patients to consult our group of top private gastroenterologists in London. People will come if we give them high quality information about the condition.

Style: technically accurate but warm, conversational, inviting. It should be easy to understand to a reasonably intelligent person. We would like to have headings, sub headings, short sentences and short paragraphs.
Please use bullet points and bold and italics to highlight key information.

It goes without saying that we do not wish keyword stuffing to be used. When there is more than one keyword per page, the main keyword target is in capitals in the document, and the other keywords we just want used once or twice in the hope of winning some traffic for them too.

If you require any more information, please do let us know.
