You don't say whether you're a long-legged, short-torso'd type or the opposite. If the former, try WSD frames; the latter, mens/unisex frames. Some people do have to go custom, but the majority of folks of your height should be able to fit a stock frame, with possible changes in stem, seatpost, handlebars to dial in the fit. I'd bet that you can fit a stock frame unless your proportions are extremely unusual.
