How to search for people for internships at FrontEnd?

Question

Personnel Management

The team has a couple of extremely experienced people, but not enough hands.
At the same time, at the moment there is no way to ensure the hiring of serious professionals. So the idea came up to arrange a mutually beneficial exchange - to take a couple of interns, without pay, to help with some simple time-consuming tasks, and in return train them to a serious level and share experience.
Where and how best to look for people for internships, bulletin boards, student groups, something else?
What conditions would be appropriate, other than the exchange of aid for training?

Answer 1

Distribute flyers at universities

Answer 2

there is no way to ensure the hiring of serious professionals

Where does the money for trainees come from then? This is an extremely costly event.

Answer 3

In computer academies you will only be welcome. They usually promise students an internship by the end of their studies and are always happy to cooperate.

Answer 4

I'm ready.
