Choose speakers first - as good as you can afford, but the TYPE of speaker (box, horn, panel, omni, etc) has to be determined by your room features. Home demo before parting with cash, as speakers needs to be happy in your room - or is it vice versa?
Do you really want to limit your potential sound quality by allocating a large chunk of your budget to a turntable? How often do you listen to records? I suspect that to match the sound quality of good streaming, a turntable / arm / cartridge / vinyl you'd have to spend half your budget on that one source! Then you'd be let down by your "cheap" speakers, amp, etc!
Consider ditching the TT idea and concentrate on streaming. My system is simple but only slightly over your budget. It consists of excellent £20K speakers fed by a bargain £5K all-in-one streamer, radio, DAC, DSP RC, amp. It’s simple and does everything I want, but no vinyl as this would halve what I could spend on the rest. Peter
