Two very good relatively inexpensive Canon lenses that will give your daughter a good kit are the 18-55 and 55-250 zoom lenses. You want the STM version of those lenses.
Since you have a 450D I am assuming you are not in the US. In the US Canon has an online store that sells refurbished equipment at a good discount with full warranty. I’m not sure if a similar situation exists in your country.
Sorry for disappointment.
