If you are new you should never, ever start off by casting spells. And most people on here do not cast spells for others.
If you would like to cast a spell yourself then you need to learn the basics such as meditation, centering, grounding, energy manipulation, and visualization.
These can be searched for in the forums or by using the search bar in the upper right hand corner.
This does take time. Those who have practiced the basics that I mentioned for a few years still have not cast their first spell. You need a good, strong foundation to build off of.
