Quality
Prontaprint are quite good for quick and small runs such as this. Just ensure that what they've sent you is the print resolution version - ie not a PDF that is set for screen viewing only - what looks good on screen doesn't necessarily print as good. If your cousin is a graphic designer used to doing final artwork you should be fine, but as someone who works in the industry - and has NO connection to Prontaprint - I have to say that we get an awful lot of logos & pix sent to us for print that people have pulled off a website and think that will work for print.
