I read your interest in finding a tutor. This is exactly what I offer on freelancer. I am not interested in writing papers for people, but am interested in assisting with needs as you work on your proposal, dissertation, etc. I typically advise people on statistics and quantitative methods, but have also conducted interviews and am familiar with qualitative methods. I have a Ph.D. in the social sciences and am currently a professor who does freelance work advising students, corporations, lawyers, etc. on statistical and other social science research needs. I have recently done work on finance and asset allocations portfolios. Please contact me and I will provide a link on this work. I am also currently writing multiple articles and a book about the 2008 financial crisis and political economy.
For the tutoring/work I do, I usually charge $100/hour, but am willing to charge you a little less at $90/hour as I saw your budget was a little smaller. I realize this is higher than your budget, but to get the tutor willing to work with you - with the expertise and experience you need - you are going to have to pay more. I can skype and talk through your project and assist you in a tutor/advisor role if that is what you are looking for. I would like to talk more to see if I can assist and if you have questions or want more information. Please send me a private message and I can provide my phone # or we can skype for an introductory interview before you commit.
