Create a 'showroom', virtual through network screen sharing or physical if possible. Demo machines where you can let customers get a bit of immediate experience with GNOME, Xfce and possibly something more. You can walk them through checking their email, creating a document and doing a bit of web browsing.
Don't front 'Linux', it's a tainted word that is of no use to typical public sector and small to medium business people, preferably don't mention it. Instead talk about your solutions being secure, cheap, enterprise grade, customisable, long term supported, things like that.
