If you don't mind secondhand I'd recommend
MPB Photographic too.
There are a few well respected retail outlets for second hand equipment, but MPB is the only one I have personal experience of and I've had excellent service whenever I've used them.
If you're on a budget you should be able to get a second hand entry level DSLR and kit lens within the £150-£200 price range.
If you're serious about starting a business in photography at some stage, you'll probably want to upgrade in the future but that should be sufficient to get you started in the world of DSLR photography.
There's a bit of a wait until you meet the criteria for classifieds here, but you probably wouldn't get massive savings over what you could buy elsewhere anyway.
p.s. Which college are you studying at?
