241914 Live Chat Script Installed

I have a new cre loaded site which needs the live2support script added to it. The script needs to show on every page view and needs to be small enough to not intrude yet large enough to read. I paid a script lance referral to set my site up since I know nothing about these templates, and he either doesn't return my e-mails or responds but does nothing ( anyone want his name for reference, let me know)
