Why not just get some used 10 speed stuff? 7 speed 1x may be a pita in terms of chain drop. are you planning on running a keeper of some sort? I ran 1 x 6, then 7 then 8 and finally 10. Even without a clutch mech, and using a badly worn NW, haven’t dropped the chain since building. Dropped chain regularly on the other setups. That and wider range of gears, better shift all adds up.
Want me to keep an eye out? Or are you after relatively high end 1x7 parts? I have a couple 7-speed parts but planned to rebuild the Specialized with them to sell, over a week lots of bikes end up at the scrapyard so I can keep an eye out for useful 7S parts that I can hawk you for a low price. MTB or Road setup? Rapid fires, thumb shifters? Wheels are a pain to post.
