EPS is Encapsulated PostScript. If you have Photoshop, you can just Save As and specify Photoshop EPS as the type. What software do you have access to?
Sorry, I do not have Photoshop. I do have After Effects. Will that work?
I doubt it, but since you're the one with the software it's easier for you to search the help system it came with than it is for me. If this is a short term project, then why don't you download the 30 day trial version of Photoshop and just use that?
