Seeking internship opportunity

I am looking to work for an agency for free on some real projects for clients, so I can showcase these projects in my portfolio and enhance my experience in the context of real projects.

During my training, I have executed numerous projects that contain integrations and advanced features. I have also built a number of plugins for these projects. I am willing to take a test before being accepted, if the agency desires so, and I do not require obtaining paid work later.

I would be happy to communicate with you if you have an opportunity for me (text communication only for English, speaking for Arabic). I would also appreciate any tips on how to obtain such opportunities.
