Two years is plenty of time to get on your dream tattooer's waiting list ;).
As far as one shot pieces - roses, anchors, lady heads, skulls, snakes, daggers, panthers, eagles - I guess anything can be a one shot done small enough, but apparently I immediately default to traditional, haha. But those pieces can loan themselves to one shots and still be sort of cohesive in the end, when you have a bunch of them.
