There is no need to buy special bonsai seeds. In fact, there is no such thing! A company selling their seeds with this label is merely using a marketing gimmick. Any seeds or seedlings can be used to start a bonsai tree.
All bonsai trees that you grow are the same species that you would see in your yard. They are kept to miniature heights with careful maintenance. The tree is planted in a very small pot, and the roots and branches are precisely pruned. This process occurs over many years.
