Hermione would be a likely first employee. She's intelligent and organized, perfect for handling complex tasks in the factory. Ron could also be there, helping with the physical aspects of setting up and managing things. Hagrid might be involved too, perhaps in charge of getting some of the more unusual or dangerous ingredients for the factory's products.
The first employees could be some of the house - elves. They are used to hard work and have magical abilities that could be very useful in a factory setting. Harry, being a champion of their rights, would ensure they are treated fairly and paid well. Additionally, some of the older students from Hogwarts who are looking for a job after graduating, like those from Ravenclaw who are good at inventing and problem - solving, might be among the first to join.
Dumbledore (if he were still alive) could be an advisor. His wisdom and experience would be invaluable. Also, some of the Weasley family members like George, who already has experience in running a joke shop, could bring his business acumen to Harry's company, helping with sales, marketing, and product design.
In the fanfiction, the first students could be a mix of young wizards and witches who have shown exceptional magical abilities but didn't fit into the traditional Italian magical schools. There might be a young wizard who has an affinity for ancient Roman magic but was not encouraged in his previous school. And a witch with a talent for transfiguration but was bullied in her old place. Harry Potter's new school in Italy could be their new home, where they can explore their magic freely.
Perhaps it's a girl orphan who was found wandering near the Forbidden Forest. She has no memory of her past but shows great potential in potions. Harry feels a connection to her because she seems so lost, just like he once was. So, he decides to take her in as the first orphan in his new orphanage.
It could be his loyal owl, Hedwig. She might be staying with him in the attic, providing comfort and also being a messenger for him when he needs to communicate with his friends outside.
It could be Hagrid. He loves all kinds of magical creatures and would be very interested in seeing what Harry has in his pet shop. He might even give Harry some advice on taking care of the more dangerous ones.
Well, in fanfiction, Neville Longbottom could be one of the visitors. He and Harry could exchange gardening tips as they explore the manor's gardens. Additionally, Dumbledore's portrait might be magically transported to Potter Manor, and he could offer his wisdom and guidance to Harry as he lives in the manor. And of course, Hagrid might come with some magical creatures to show Harry, adding more excitement to the manor.
His friends from Hogwarts, like Ron and Hermione, are likely to help. Ron could bring his family's practical knowledge of wizarding homes and Hermione would contribute with her extensive research skills.
Hermione would be a great help. Her vast knowledge of magic and books could provide the necessary information for building the planet, like the right spells and magical theories.
He might meet Canadian witches and wizards. There could be a friendly wizard who shows him around the Canadian wizarding community.
He might meet international aurors. These are highly skilled wizards from different countries who are experts in dark wizard catching. They could teach Harry some new combat spells.
