Develop a Mac Application

I need someone who is quite skilled in applescript and apple apple file formats to write a script to copy the file names in an iphoto library into the 'title' field. That is, if the title is blank copy the filename into the title (without the .jpg extension). My client has a large (150g) photo file; when opened in 'photos' it doesn't show titles; when opened in iphoto it does because iphoto uses the filename as title if the title field is blank. I think this is a simple apple script problem; glad to pay market programmer rates to have a well debugged script. 150g file available for download or on HD. I found a script online that said it would work but it didn't work on the large photo file. Help?
