Looking at your criteria I think I can help you. Counselors do not always work for profit motive. It really depends on who you are approaching. I am myself a professional consultant. I have done my MBA from US university and have worked there for 3 years. I pretty much know about the admission process and the things schools look for in an application package. It is not just GRE or your GPA for that matter that will be considered alone. Its all together- your GPA, GRE or GMAT, TOEFL, LORs, SOP, Resume, etc. Also your publication will help a lot in getting TA/RA.
