If you can find the time, which I understand can be almost impossible if you're working, throw together a small portfolio and vanity site. I've landed a few gigs just by saying the right words, others by having something shiny to show non-tech folk or having at least some code to show that I am not full of shit to technologically competent clients. Hell, I landed more than one gig from blog posts about technology (relevant to clients) I wrote in high school.
I don't have a record, but it's never come up nor have I been given any hint that a background check was performed.
