Custom Photoshop Action or Mac OSX script

I'm starting up a t-shirt company and I need to print up thousands of images of my shirts. All my shirts look the same (same logo) with the exception of a different title under the logo. Currently, I use a template in Photoshop and manually type in the title and then save the file. As you can imagine, this is very time consuming. I'm hoping to automate the following: STEP 1: Copy one title from an external source list (spreadsheet, Word doc, etc) STEP 2: Paste the copied title to the Photoshop template STEP 3: Save the Photoshop file as a JPEG using the title name (e.g. [login to view URL]) STEP 4: Go to the next title on the source list and repeat IMPORTANT NOTES: • Has to be able to run on OSX (I use a Mac only) • The script should have some sort of a width boundary built in so it knows when the text is too long and needs to break and use a second line (so it fits on the shirt) • All the title names begin with the same word "likes" and then follows with the title name. However, the word "likes" is a different color and font than the title. I don't care if it's a Photoshop Action or if it's some sort of OSX app, just as long a it works.
