Hi Greetings,
I have experiences using labeling software, usually i use codesoft and then sometime i use nicelabel. For bartender i have once time experiences using this for my project (labeling project for industrial packaging).
I think all labeling software has same feature, such as function, variable, logic (visualbasic script) and date and have four main item (text, barcode, image and line).
So I think I am the right freelancer you can hire on freelancer.com.
