Another way to save money is to think well about which props you need, and without which you will, quite, do. You don't need to grab everything, and only then think about whether there will be an element with this equipment in your number. Watch bubble show artists' videos, consult with more experienced colleagues. And even better, attend a master class (Forms of training), where you can try to work with the props and understand whether it is yours or not. Or you can learn bubble show by yourself (Basic video course).
