Posters - from Xara to print help?

[Jon G]

Hi,

I need (won a competition ) to do 18 language versions of an A3 full-colour poster. I made the initial version with Xara, but the Bulgarian printing house wants .eps, they say pdf is no good

but ok, it's a very simple poster consisting of:

- one photo, faded into background from the upper part
- assorted logos placed on the photo, different for most countries
- the main vector logo of the association
- text

Now I have Photoshop Elements, and I think I could use that for making eps files.

How would you proceed with this, I'm just a beginner and could use some pro help- thanks.
