Help with creation a portfolio

Hi, peeps

I’m looking to find some corporate experience in graphic design so im looking to develop some of my work and create a portfolio… But I haven’t got a clue how? I mean, I don’t know how to structure one, should it be A3 or slightly smaller?

Should it be like those design technology projects u did at school? (UK)

Basically what I need from you guys is any information or hints you have to help me build a spanking Hot Portfolio?

ANYTHING may be in your portoflio, but put only your best work - ask friends and relatives which ones they find the best. Be sure to know why how and what you did in each piece of work (in case your asked by someone who knows lots about art) make sure it’s clean and make it ‘different’ if you can, have your own style, but that’s the tough part, can’t helpya there.

here’s a few sites I found on google about it; (search for more, google is your best friend)
