You mentioned that you would be willing to buy the frame then wait to build it up, that's how I acquired my Italian Bianchi, bought the frameset first about two years ago, and just finished building it in February (actually I haven't shared the finished bike here yet, I need to do that!). Since it sounds like it'll be hard to find the bike you want at that budget I'd recommend this approach
