I need various articles researching and writing (UK immigration law)

Kind of writing: Politics
Num. of articles: Many!
Words per article: 1000-5000
Industry: Legal
Topic: UK Immigration Law
Tone: Formal/Professional
Outline & Structure: I need some topics researching and writing up for my website which is to host simplified information regarding UK immigration law. The information is to be taken from https://www.gov.uk/browse/visas-immigration/ but re-written and simplified where possible. The topics to be covered are:
1. Study Visas
2. Short Stay Visas
3. Transit Visas
4. Work Visas
Al above topics are to include categories and their respective requirements, and how & where to apply. These articles can be split up into several articles, or formatted to display several categories of visa in each article. All necessary information must be included.
Final topic to be covered:
5. Stateless Persons in UK immigration law
Extensive research needed: yes
Extra notes: Main objective of these articles is to simplify the information on the .gov website so it can be more easily understood by people who's first language isn't English. Any jargon is to be explained in simple terms and tone is to be slightly more informal. Send me a proposal for price!

Thanks in advance.
