Hi BM

I put together this document (it is available in PDF acrobat format) specifically to answer this question as it comes up a lot. The advice from your peers above is excellent - look at what others have done in your sub-field. Consult dissertation proposal journal articles written for your field or sub-field if you can find them. Please see the first link. Regarding so-called essay writing services. Drawing on my background as a qualified accountant and economist, I conclude that there is no way any of these ghost writing services can possibly produce polished original work unless there is some trick such as copying as pasting text (which Turnitin will detect), copying work in foreign languages (Turnitin will not detect) or outsourcing it to a developing country where wage rates might be a few dollars an hour. All such uses will result in instant failure and likely expulsion from your course. The amount of work involved in any form of original research is a lot, and you usually need to write numerous drafts and edit them many times to reach doctoral standard. This is what makes academic research and writing so rewarding. Only 10% of the work you actually do may appear in any document such as a thesis or research proposal. I hope this helps.
Best - Jay
