Linda,
Check the PageMaker prefs and select the hi-res option.
Stick to high resolution TIF for PageMaker.
You can use EPS.
Gif is only suitable for web.
If you are creating the work in Illustrator, just make up one card.
Give the native Illustrator file to the printer and let him do the lay up himself. It will only take him seconds.
He may have a preferred layout for trimming. As well as format and resolution.
This is more easily done from the Illustrator file.
Just remember to 'Outline Text'. This cuts out potential font conflicts.
Also, he may not use PageMaker. If he uses Quark he will have to convert the file. More Work!
You will have have to supply the file with the PageMaker document anyway.
Keep it simple, give him the file which he certainly can use.
He will love you if you give him this flexibility.
(I would!

Al.
