Seems to be akin to an art / music job. Built a portfolio of photo shoots. Homemade with friends is fine as long as it seems good. Before looking for work, gather opinions but don’t believe people who tell you you can’t because you can.
Act like you’ve already made it. Fan page. Website. Whatever. Look like you’re somebody already. All about the image – the reality behind it doesn’t matter.
That’s generic advice I’d give for any art/music type stuff but applies.
