Need an experienced Biomedical Engineer to teach me concepts I can learn in an internship

I am looking for a biomedical engineer who has worked in Indian hopsitals who can teach me everything one learns during internship at hospital. I have exams in a couple of months and I need to be prepared about this subject. I will have some questions of my own. Price will be decided upon the level of experience of person applying and the depth of knowledge they can provide.
