Hmmm, your question is a little bit complicated, a lot of students face some problems. But if I were you, I would try to find some companies in my area, which would be relevant to your experience and field. Then I would find some contacts or go there personally to ask if there is such a possibility to work/to volunteer. Send as many emails as you can, and, sure, you will find a company or an organization which will help. This is not the best variant and it is quite a time-consuming one, but you can try to do that.
