Theres no spell that will get you money instantly.You will have to actually work to get that money.Spells are an aide,not something to rely on.
That being said,write you own spell!
Its easy,personal,and more powerful.
Incorparate colors of wealth during your spell (gold,green,silver)
and ask deities of wealth.
Try using a dollar or coin in your spell too.
If you dont know how to write your own spell,perhaps you need to do more studying.
