Copywriting and editing - email newsletters, blogs, press releases, and social media posts

I'm looking for someone to help with a variety of copywriting projects including email newsletters, articles, blog posts, press releases, landing pages, and social media content. Topics include healthcare, technology, and nonprofits. Editing experience is also a plus, particularly editing audio transcriptions. The workload will vary from week to week and month to month, probably starting with a few hours per week with the potential to increase. I prefer to pay per assignment rather than hourly, but since the projects will vary, hourly rate is a good placeholder. Let me know what experience you have with these types of writing and include 2-3 writing samples. Please, no generative AI in your samples, cover letter, or profile, as I expect you not to use AI for writing if I hire you. Thanks!
