I have finished my bachelor's degree, and started out with my master's degree in business. I have participated in several research projects as primary assistant. Now, I am thinking to start offering assistance services to PhD and Master students for their research projects (Transcription, Data Collection, Literature Review, etc.). As PhD and Master students, do you think that PhD and master students are in need to these services? Is it a good business model? Please give me advice/opinion based on your experience or role. Thank you!
