Gold Saucer coming in 4 months or so.
Till then, considering your lvl, there really isn't that much to do, unfortunately. Except maybe running Ifrit and Titan just to randomly help people out.
Or you could do Guildhests.

You can also start doing lv40 maps soon, though that would need a gathering class high enough to get them.
Actually, lvl a gathering class, maybe fishing as Torao suggested, quite different from DoW/DoM lvling.
