Writing Tutor Needed

I need a super nice tutor to help my son (14yrs old) & my daughter (13yrs old) get better at writing since my son getting ready for high school. The tutor should know a lot about writing stories and essays and how to make paragraphs that make sense. My son needs help with his writing, and it would be great if the tutor can make writing fun! I want someone who is patient and can explain things in a way that makes it easy for him & her to understand. If you really like writing and can help my son & daughter learn and have fun at the same time, I would love to hear from you!
