Adobe Illustrator Coder Needed to write small script -- 2

I have an illustrator file (contact me I will send it to you, its very basic though) It has a layer with a text box with a number combination like `2R10-000`. I need a script to change the number after the dash based on a range and save it as a file. Like: 2R10-000, 2R10-001, 2R10-002, 2R10-003, etc.. Notice the number is padded with zeros, this is important. Before the file is saved the letter-spacing needs to be changed on the text box layer. The letter spacing is based on the number of characters in the text box because there can be either 6 or 7 characters. But it's also based on if the text ends with a 1 or not. Here are the rules for you to follow to apply the letter spacing: 6 chars + no 1 at end = 86 6 chars + 1 at end = 106 7 chars + no 1 at end = 26 7 chars + 1 at end = 46 After the change is made, the file need to be saved with the same name as is in the text box like: [login to view URL] or [login to view URL] After I run the script I should have all the files in a folder within the range i specify in the script. I don't need anything fancy I can make adjustments needed once I have a good starting point. To summarize: 1) Loop a number range 2) Edit text layer 3) Adjust letter spacing 4) Save new file
