Glad you're finding my videos helpful! I recommend checking out Parker Dewey for short-term paid project work with companies. I talk about this more here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-2--Yv8oNt_Q.html
3-4 months before I started to follow your channel, I applied to 5 companies for voluntary internship, but I did not get any response from any of them. I came across a video of you, listened to your word, and found people interested in recruiting at the companies I applied to. Some of them are on the company's board of directors, do you think they are the right people to contact?
I live in a small area and some companies I applied for have only 3-4 employees, do you think it makes sense to go to the company and meet face to face instead of emailing?
If you've graduated, I would move on to looking for full-time jobs, not internships. There are some companies that offer rotational programs (which are like a cross between internship and entry level job), and that could also be a good place to start if you're not sure what type of work within a company you want to do. In regards to applying to companies that are not currently hiring - I talk more about how to approach that in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-gMnL37px9EU.html
