DnD Master for 10 year old Birthday

After binging Stranger Things over the holidays, our soon to be 10 year old son has become obsessed with all things DnD. We got him a starter/intro set, but frankly I have no idea what’s going on.

His birthday is coming up and something that I thought would be cool is if we could find someone/place that could host a quest/adventure for him and some of his friends.

I figure Chaotic Good is my best bet, but figured there was some overlap in the Venn Diagram that is DnD and Reddit.

Any recs would be appreciated.
