You need to understand that people can't cast spells for you. We don't know you in real life, so we've no access to your energies. I doubt you'd travel to one of our houses to cast a five-minute spell that may or may not work.
You need to make one and cast it for yourself.
If you are in dire need of spells, we've plenty of them. I can spare a few from my book, if you'd like. I would have you PM me for them.
Like the others said, to do work for you, we'd need a lot more information and would need to get permission from the spirits to pry into your life to do a spell. I, for one, am not qualified to do that. I can give you a recipe for hot foot powder or recommend a spell you could do yourself to get someone to back off, but that's about it.
