a mirror is so to speak a local copy of one or more repositories from
the internet. There are tons of tools for creating a mirror. The package
named apt-mirror seems fairly simple to use. You just have to specify
which repositories from which servers you want to copy. But be prepared
that you have to download a few gigabytes (depending on which 
repositories you choose) of packages if you run apt-mirror for the first
time. Then you can make the packages available via your local
webserver. And put the url into the source.list file on the client. This
method is preferable if you have lots of clients, because you generate
external traffic only once while building the mirror. Every client
installation only generates local traffic. 

If you only have few clients and the ocs inventory agent (and its
dependencies) is the only package you need from the universe repository,
it might be easier to download the packages manually and put them on
your web- or file-server. Then you can download the packages with wget
or some other tool to your client and install them with dpkg. This
approach might be easier to implement than a full mirror. But you have
to resolve the dependencies between packages by hand. An extension to
this approach is a local repository. This repository behaves like
ordinary ubuntu repositories, you can use apt-get, aptitude etc. with
them. In short: you throw some .deb packages on a webserver and use
tools like dpkg-scanpackages to generate meta data like the Packages.gz
file. If you search for 'create own debian repository' you will find
dozens of howtos. It's no rocket science to build your own
repository. But you need to read a little bit and try the steps a few
times.
