You'd be surprised how little some of these businesses know. I have previously; - Built a travel database in MS Access for a Travel Agent (long time ago) - Ordered and setup ADSL connections and email for a water tank manufacturer and a furniture store - Capture requirements, researched, ordered and installed an office (6 people) worth of IT kit for a not-for-profit (didn't charge them for this work). - Designed and implemented a roster management system for an IT helpdesk for a university.
There are heaps of opportunities. Just have to know where to look.
