Add a subtitle to my book :)

I am looking for a skilled freelancer to reposition the images and add a subtitle to my two non-fiction book front covers (attached in jpg format). The book falls under the genre of non-fiction and has an educational/instructional theme. I have specific words and ideas that I would like to be included there.

Ideal skills and experience for the job include:
- Excellent background in Photoshop
- Strong writing skills with English and Arabic updated fonts
- Experience in designing book covers.
- Understanding of educational/instructional themes
