When you have people who ask to be paid for casting spells for you it's most likely a scam to just get your money. I suggest not falling prey to this and learn how to cast your own spells. And they probably won't even cast the spell anyways. And if, for some reason, what you wanted to happen through the other person casting for you happens it's probably because of mere irony. Or from pure coincidence - if you prefer that over irony. Also you risk them casting spells that can make things fall negatively - the opposite of how you intended. These are risks you take. So be very wary when others cast for you, especially those who expect to be paid. Again, I suggest not faking prey to these scams.
As stated above, you can use tarot cards to find things out. If you don't have any you could make some, or even use playing cards to represent tarot cards - if you'd like. There are other methods you can try as well; such as scrying or rune divination.
