InDesign - that's the way forward.
I believe you can download a copy for trial, and if i remember, you help out or study at a local college, which means you can get a copy at a substantially reduced price.
It's easy to get the hang of, but much harder to actually master to a pro level. But that's only because your document is processed in layers, as is your picture in photoshop.
EPS is a native file format, and it really does make life easy.
Ah, had I only known. My daughter used Indesign at college I'd have gotten her to help.
Since I'm pretty much starting from scratch I may do that.
