Should we move to South Korea? (Seoul)

My husband has a job opportunity where he will be based in Chinhae for 2 years. Myself and our children (2 and 5) have the opportunity to go with him. His company will put us up in accommodation. My concerns are 1) will I be able to find a school to educate my eldest child 2) will my children settle into South Korean life and 3)will I be able to make friends. Great to hear views of people who have been through this.
