Small business IT security

[jonathan () gatewaysa com]

Hi

I dont know if this is the correct place to post this. I am doing some work for a small company with around 80 pc's. 
They dont have any inhouse IT staff and use an out side little computer dealer for all their work. These guyse look 
after everything from the pc's to the servers to the network. They obviously have all the admin passwords etc and if 
somehting needs to be repaired they take it to their workshop where one of the technicians will repair it. This It shop 
also does work for one of the competitors as well as a few customers.

I know all the security risks but short of hiring someone in house what else could be done to ensure they Information 
Security.

Thanks
Jonathan
