Well,Courtney. There is nothing hard about casting spells if you understand what a spell is.
A spell is a ritual attempt to obtain a magical result. A spell is not magic of itself!
Most people have cast a spell at sometime, sometimes without ever knowing it!
If you have ever blown out the candles on a cake, and then made a silent wish, you have cast a spell. Ever pulled a wishbone? That's another spell.
You don't need a spell caster; they are usually fake anyway. Write your own spells!
Blessings from an old witch.
