Tearing my hair out - create alias to import to iTunes

Ok, what I'm trying to do is this:
1) Monitor the Movies and TV Shows folder on my external HD.
2a) If an mkv is added, run iFlicks and remux it as iTunes Compatible then delete original file
2b) If an avi is added, run iFlicks and convert it to Apple TV/iPad format then delete original file
3) Create an alias to the newly created m4v file and place it in my "Automatically Add to iTunes" folder
4) Delete the alias from said folder
Step 3 has to be done like this because I don't want to copy the movie/TV show to my iTunes Media folder when importing. Otherwise I would just use iFlicks Import command. The only way I know of to programmatically import a file to iTunes whilst leaving the source file in place is to place an alias in the Automatically Add to iTunes folder.*
1, 2 and 3 I have managed myself but what happens is the same file gets imported into iTunes many times. I need a way of deleting the alias from the AAtI folder after it's been imported.
*I'm aware there's an option in iTunes to turn of Copy to iTunes Media folder, but I don't want to turn this off, because my books and music etc DO reside in my iTunes Media folder and I like iTunes copying them there automatically.
Many many thanks
