SEP deploy to a remote site

Hi all, 

Having a little trouble with using the management console to deploy to a remote site. 

I can connect to the servers and user computers fine, but the speed of the line down to it is too slow.

I have heard from a few people that i can create a local repository and use the management console to tell PC's on that site to get the install files from there. 

Would anyone be able to offer some advice on how i might do this, or where i can set this up from? Or is there a way of package creation so this can be installed onto the slowband machines individualy?

Thanks
