Article Rewriting for Readability

I have around 15 articles that need to be rewritten in proper English grammar and simplified for a 13+ age group. The freelancer must be based in the UK and ideally hold a higher education degree.

Skills and Experience Required:
- Excellent understanding of English grammar
- Ability to simplify complex sentences
- Experience in rewriting articles
- UK based freelancer

Please note, the subject matter of the articles and the tone or style would be communicated upon project commencement.
