1. First, optimize your own workflow and time allocation to improve work efficiency. You can use time management tools to make a priority list, arrange tasks reasonably and improve work efficiency.

2. Secondly, establish cooperative relations with companies in other industries to undertake projects or recommend customers to each other. You can also outsource non-core business to professional service providers to reduce your workload.

3. Then, you can ask volunteers or interns to help you complete simple tasks or daily work, which can not only reduce your work pressure, but also provide volunteers or interns with opportunities to learn and practice.

Finally, if you think it is necessary to hire employees, but you are worried about the cost, you can train and upgrade the existing employees' abilities, so that they can be competent for more tasks and reduce the demand for external employees.
