Chiming in with more low budget suggestions!
You don’t have to have any tools. They can be helpful but they’re not necessary. Your athame could be a letter opener or kitchen knife that you dedicate for a different use. Your wand could be a branch, a paintbrush, a kitchen spoon, I use an old drumstick because I play drums. Your book of shadows (or book of mirrors) can be an old college notebook, and so on…
It’s not the tools, it’s the Witch!
