writing a research manuscript

I am looking for a freelancer to write a research manuscript on a medical topic with an observational study. The manuscript should have a total word count of less than 3,000 and must include thorough research to ensure accuracy. The resulting document should be well-structured, well-written, and have clear and logical conclusions. The freelancer must be able to provide proofreading services as well as revisions when required. It is important that the document is completed on time and within budget. Please provide samples of work to demonstrate relevant experience and capabilities prior to making a bid.
