Hi Jazmin! If it’s for a talent agency or a specific production company, try this:
- Recreate their business card but add your name and information instead.
- Burn a green or yellow candle on top of the card as you meditate on your goal. Focus your intent and imagine everything going well: Visualise it, feel it, manifest it.
Tonight’s Full Moon is on your side! 
Check your local time and try to avoid casting the spell during the lunar eclipse. If you have bay leaves, add burning a bay leaf with your intention to manifest it faster!
You could also craft a sweetening jar such as this one and add the name of the company or person in it (e.g. judges, interviewers).
I would say maybe the most important thing is that you work on your self-confidence and calm your nervousness. It sounds like you have good chances so don’t let your own fears/anxiety hold you back!
Best of Luck!!
