This mainly depends on the size of your venue, not just the stage. First of all, how to match the sound, the size of the venue is very important. If it's open-air and different collocation methods, if the sound is good, almost two sets will be enough. If the lights are bright, four beams shake their heads. If the budget is enough, you can add a little more, and the effect will be better (such lighting effect is acceptable). The background truss, inkjet and LED screen can be used. If the budget is enough, you can consider using a mirror carpet on the stage runway. The lighting is really beautiful. As for the price, I can't calculate it for you, because the market in each place is different and the price varies greatly. You should know that the quality of the host is very important. If the host is not good, the game is over. Please carefully screen! If there is anything else you need to consult, you can ask directly. I am also engaged in weddings.
