I am a researcher at McMaster University.  I was wondering how much it cost to buy a photo?  I was also hoping that  you would allow me to use one or two of your photos for research purposes for free?  I work on reproductive eoclogy and conservation of fishes in Hamilton Harbour and Cootes Paradise.  You have some lovely shots of the harbour and the marsh from the air which I would love to use in talks.  
In particular I am keen to use #001, #004 and #005 on Flight Date 26 May 2002 | Roll/Negative #04/16 | Photo Compact Disk # 
Hwy 403/Cootes Paradise, View East
Thank you so  much in advance for your help.
