Re-write pages for website

I have just duplicated parts of my website, and need someone to re-write parts of it, so that the content is not counted as duplicated content. I run a care website, and will need the following pages to be re-written:

Dementia and Alzheimers
Elderly Care
Live in Care
Night Care
Palliative Care
Personal Care
Disability Care
Reablement Care

The above pages need to be 200-300 words long, and I already have pages written up for them. I also need the following pages written up, (these will be new content).

- The cost of live-in care vs a care home - ie. https://myhometouch.com/understanding-the-cost-of-care
- Understanding live-in care - i.e. https://myhometouch.com/understanding-live-in-care
- Waking night care explained
- Sleeping night care explained
- Why become a care assistant (i.e. its rewarding, its community orientated, its sociable etc.)

Can you say let me know how much it will cost to write all 13 pages.

Many thanks,
