I need a programmer for batch scripting

I'm an engineer. I need to make two scripts. I have files the need revision level added and moved to a destination folder. For example, I have named: [login to view URL] [login to view URL] I need to move them and add revision level: [login to view URL] [login to view URL] where REV are sequential revisions [NEW, A, B, C, D.... etc] I need two batch scripts: 1. For each file in a working directory, check if this file already exists in a destination directory. If it exist, check the revision of the existing file, add the next level revision to the new file, and move the new file to the destination directory. 2. For each file in a working directory, check if this file already exists in a destination directory. If it exist, check the revision of the existing file, and replace the existing file with the new file, and add the same revision level to it.
