Best school districts within 45 mins of the coast?

My family and I are moving to SC in 2025. We are a bit limited where we can go as we have to stay close to the company my husband works for. The only other major consideration we have is the school district. We have found Fort Mill. It’s looking perfect for us, and yes I realize it’s not on the coast. My husbands company has locations in Charlotte, but also on the coast. We’re not sure where they are going to have an opening yet. So I’m looking for the best school districts along the coast or within 45 mins inland. People have already mentioned Charleston County, so I will look into that. Any others that are decent? Rent under 3k is needed.
