Much better idea.

As long as you aren't using overlapping scopes, you won't have IP address
conflicts. But note that (internal) dynamic DNS updates will work a lot
better if you let the server handle it - you don't mention whether you're
using a domain/AD, but if you are, I'd definitely let the server handle
DHCP.

It should be a pretty simple procedure for them. They shouldn't change the
LAN IP - just disable the DHCP server.
On your server, I'd set up a scope from 192.168.1.1 - .254 and exclude .1 -
.50 for static addresses and maybe also .200 - .254 as well.

Not sure how to do so other than I have!
