Spells are simply prayers with attitude. Intent is all-important. The things you use in magic such as Chants, candles, talismans, cords, etc., are there only to help you focus your intent. They are like personal props an actor uses to get himself into character.
If you can't find a spell that you need, simply write your own, just be clear about what you want. Take your time and really think about what you want to do. Just remember 'An Harm None'.
It's always good to keep track of the spells you perform. This will help you later determine what went wrong, or simply help you determine what you did right. :)
