Hello,
I've been writing for Mac since 2009, occasionally publishing to the app store. There's some past work in my portfolio. I'm not too well-versed in AppleScript but if necessary will make it in that language, in any case I'd love to work on a demo version of an application before any project assigning and the likes.
If you give me examples of file1 and file2 I can start writing something to automate the process, give the demo, and then finish up through Freelancer if you're happy with the result.
All the best,
Bruno
