You agreed not to bump posts when you registered; nobody here is "on call". If you really, really need help RIGHT NOW there's even an "emergency support" forum you didn't use too.

It would help a lot to know what your system and shell is.

Run this in its own empty directory to see what it does. It should work in most shells. You can probably adapt it to do what you want.

Code:
#!/bin/sh

# Create some example files to work on.
# it will create directories 00 through 09.
# 00/ will contain files 00-00 through 00-99,
# 01/ will contain files 01-00 through 01-99, etc.
for DIR in 00 01 02 03 04 05 06 07 08 09
do
        mkdir -p $DIR
        for A in 0 1 2 3 4 5 6 7 8 9
        do
                for B in 0 1 2 3 4 5 6 7 8 9
                do
                        touch "$DIR/$DIR-$A$B"
                done
        done
done

# Let's list all the 00-* files, and split the list apart at 20 lines each.
# The 'split' command will create files "list-aa", "list-ab", and so forth.
# the 'sort' makes the filenames come out in order from 00 to 99, if
# you don't care about that you can leave it out.
find ./ -type f -name "00-*" | sort | split -l 20 - list-
# Now we use each list to create its own zip file.
for LIST in list-*
do
        ZIPFILE="${LIST}.zip"
        zip -r "${ZIPFILE}" -@ < "${LIST}" && rm "${LIST}"
done

# show our zipfiles
ls *.zip
# how many files in the first zip?
unzip -l list-aa.zip
