I think that someone or some company could definitely share the vision that you have. That said, 25k is fair; but, I wouldn't price it. I would want them to come to me and start negotiations. I think a lot more is on the table when you're dealing with someone that has the vision of taking this to the #1 resource for kids as there's a lot of money in the space, be it language and learning to e-commerce to a clothing brand.
2500-5000 if you want to flip it quickly though as it's not just any LNL
