I am looking for a professonal writer

I am looking for a professional writer to write, rewrite, and proofread our newsletter, correspondence emails, and other content for a young not-for-profit arts organisation. You will need to sound exciting and persuasive and know how to address stakeholders and sponsors. The content needs to be descriptive, and visionary and should aim to be engaging and encourage people to take action.
Our contents are around 500 words at a time or less and currently, we have around 10 subjects to write about.
Although you will be provided with the main content, you will be required to have a meeting with us so that we can describe better who we are and what we would like you to achieve through the text.
£10 per content.
