This is a subject that has been visited frequently on this board, and as recent as last week. If you have never used the search option at the top of the board "screen", it is a very helpful tool, and will provide not only current commentaries, but some very insightful comments from people who have expertise, but perhaps not the time to visit this site as often as in the past.
With that said, I think you will find that one of the boards frequent contributors, Mr. Tony Poderis has written some exhaustive articles on this subject that are displayed on his website:
www.raise-funds.com listed under 'free articles'.
I have found his information to be very rich in content, instructional in style, and of a professional level that will reflect well on you when speaking to your supervisor concerning information you have discovered.
Hope that helps!
