Hi, I am looking for a content writer to work with my team. We are a marketing agency and have clients from different parts of the world. The content writer's job would be to write Articles and Blogs for my client's website (The current client is related to immigration), and they can engage in Social Media Content writing too. Agencies pls stay away; freelancers are welcome. Pls, mention your rate per word. This could be a long-term relationship if it works out as I have new clients coming in each month.
