I've painted an album cover for a CD and now it's going to be released as an LP. The band wants me to do the whole design this time, but I have never done this before so I don't know if I'll be able to learn how to do this in time, so I wonder how difficult it really is...??? And if there are any tutorials to find about this process.

This is the CD-version of the cover:

The design in itself will be simple. I'll just add some text and stuff. It's the "turning it into something the pressing plant can use"-process I wonder about.

This is what the record pressing plant requires:

They have templates for the LP-cover, jacket and labels and stuff...

I know only the basics of photoshopping and I have never tried working with pdf or eps nor tried any design programs. On the plus side: I'm pretty good at learning stuff on my own (I've learned to paint and to make basic homepages by myself for instance).

Should I leave it to the professionals or is it possible for me to learn this from some kind of tutorial (+ lots of googling) in... say 2 months?
