I am sorry to inform you but there is no safe way of making money easy. No spell will be able to just have money appear in your life at no cost to yourself.
I would advise you not to delve to deep in this quest for wealth, all the best.
If you want a money spell, why not write one yourself?They are much more successful than pre-written spellsbut be aware that even if the spell works, you won't receive money for nothing.
Money and wealth spells work alongside mundane means to gaining money; work hard, aim for a promotion or find a better job and the money spell can help give you an extra boost, but don't expect a wad of cash to be pushed through your letterbox out of the blue for nothing.
It is probably also best to say you need to be careful what you wish for, sometimes the money gained can be from unexpected sources, not all of them good.
