Need a copywriter

Looking for a specialist to write a Motivation Letter (in English, 1–2 pages). I need someone with experience in writing strong motivation letters for international programs, funds, scholarships, or grants, who understands how such letters are evaluated by selection committee members. Important: the letter must be written without using ChatGPT or other AI tools, as the organizers explicitly state that AI-generated texts are easily recognized and automatically disqualified; I need a lively, natural text that conveys my personality, motivation, and experience; I am ready to provide detailed information about myself, my experience, goals, and answer any questions necessary for preparing the letter. It would be a big plus if you: have already helped others apply for international programs, internships, grants, or scholarships; have participated in similar selections yourself or understand what the committee pays attention to; can not only write beautifully but also construct a convincing candidate story. When responding, please include: your relevant experience; which programs/funds you have worked with; if you can show examples (if it does not violate confidentiality); cost and deadlines for completion. Thank you!
