My advice would be to compile the best portfolio you can manage. It depends what artwork formats you have, but if it's for a job I'd recommend you take a lot of time over it and spend a bit of money, too. I was told once that a designer's portfolio is their most important piece of kit, and money spent on it was money well spent. For f***s sake don't just print it out on Viking Budget paper and bung it in a 3 binder! I'd certainly look at pro binding and printing, because even a few hundred quid will be repaid quickly if it gets you a job. (Actually, someone suggested yesterday that I compile my own portfolio - at 34 years of age! Yeah, right! lol!)
