Business cards help, I'd get some printed up if I were you. You can get them done free or if you'd like to design them yourself you can pay to have some cards with a nice quality. You get better at talking yourself up over time.
I found that simply showing my photos to my coworkers (they'd been begging me for months to see the pictures) landed me the opportunity to shoot a wedding, and one of the guests at the wedding works for a company that's now one of my repeat paying clients. If I land a couple more accounts like that one, I could leave my other job at the post office and do this full time. (Actually, with some of the big projects they have me working on, I could probably leave now...but when my projects are done, then what?)
Does Image Kind offer print capabilities? I use a Smugmug pro account (big expense to swallow early on, but it's paid for itself in prints) because it takes care of all the professional printing and you can set your commission.
(Sorry for straying wayyyyy off topic, I can split this into another one if you guys want LOL)
