If you are reading this proposal, it’s a success already!
I have checked the project description. What is the name of the product? What about its length? Do you have any guideline?
I've collaborated with academics and students worldwide from the initial drafting of a research proposal right through to any stage of the research project (participant recruiting, interviewing, SPSS analysis, Systematic Reviews, and manuscript writing for publication).
I could have attached some of my past work for you to have some confidence, but there’s no such attachment option. Better if you go for the chat option and I can share some of my past work. Surely, you will have a better understanding of my writing style.
