Alternatively, set up an equal value exchange — if you need exposure you can consider working for exposure. Find a handful of companies, offer them to work for free in exchange for retaining a full byline and for the specific purpose of marketing yourself. That’s very different from when a client says they can give you exposure.
Freelancing isn’t “build it and they’ll come”.

I have done the rest except this that you have mentioned. That is working for free. I am willing to do that but I can’t find any companies here that needs my service, not in my city or country. So, how do I find that online?
