It's a good idea to make a nice portfolio on line, it makes potential employers easier to access. Just be creative and informative but the biggest problem people have is spelling, make sure you spell check it and look it over multiple times. On resumes spelling is the number one problem that potential employers look at, seems trivial but it can be the difference between landing a good job and not. Just start one up and take your time and think it through and get other peoples opinions first before you post it.
