steventoney,
Again, good suggestions from members. Record Cleaning. U.S. is best.
This site will keep you busy and your money well spent. whart and terry9 have gone the DIY route with U.S. cleaning ( A good way )
Your vinyl budget of 15 to 20k is good. Maybe a little "stretch" room if your like me and have to have it now. So...., My suggestions.
Make your move , Pick out Your speakers. Use Your Ears and eyes. You will be the one living with them!
TT = For my (3rd TT) ; I'm almost ready to pull the trigger on a Technics SL1200 G. ( Not wait for the (10R )
Use tonearm that comes with the TT.
Cartridge = So many choices and so many that I have Not heard. Pick something in 1-2k range.
Tube Phonostage = ( I use a Manley Steelhead ) It is spendy even if you find on used market. Zero problems, responds to 'tube rolling', Dead Quiet ( counts a lot with me ) Look for a Manley Chinook on the used market. All the above applies.
For "the stretch part" of your budget; Think Room treatments.
Enjoy your vinyl journey.
Best to you
