L14-30 is a pretty common fixture, maybe for an electric dryer? It supports 240 and 120 operation. The L2 EVSEs only do 240, so an L5-30 or L6-30 would be sufficient.

I have a similar socket (L6-30R - the 240V only version of what you have) installed in my garage per my request. I bought the Voltec L2 EVSE, drilled out the bottom hole, ran about 5 feet of cable (12-3 in a black sheathing, but not Romex - I'm not sure of the proper term for it) from the Voltec (through a Romex wire clamp screwed into the Voltec) to a L6-30P and plugged it in. Everybody's happy.
After looking at a wiring diagram for L14-30, if I were to do this I would leave the common pin (the narrow one) on the plug disconnected from any wire, but before I would do that I would double-check that with an electrician or even a "seasoned adult" at the Lowe's or Home Depot (grey beard == experience!) pretty inexpensively. Further, if I did leave it open I would be sure to label the plug indicating that it is not wired per the specification.
This is a <$50 self-install, maybe $100 if you get an electrician to do it. Check Angie's List for someone qualified near you. The plug is $18.00 at Home Depot, and I'd need a 5-6 feet of 12-3 cable in black sheathing ($2/ft or so) along with a connector to use in the bottom of the Voltec (a threaded Romex-style clamp - ~$2 - is sufficient for an indoor mount as the Voltec is pre-threaded, but something watertight would be required for an outdoor connection). I could have used 12-4 OR 10-3/10-4, but since it's only carrying 15A and a short run, 12ga is sufficient. I'd probably use the 3-wire cable and save a couple of $'s on the wire.
