Local machinists: I need a 10' straightedge.

Just buy a sheer if plywood and cut it in half, 8 x 2 now.
Factory edge will be dead straight.
Get a couple 2x4 and drywall screws to allow stacking and you can make it longer.

I often use a 12" x 60" sheet of aluminum as a straight edge when doing layout. It works great as a cutting guide for drywall. The problem with sheet metal is it bows easily. Then, if it is not held perfectly vertical and it is bowed, the edge isn't straight any more. It could be improved by sandwiching it between two pieces of 1x4 to stiffen it though.

Perhaps a section of Unistrut/superstrut channel would be good; the ten-foot length is available, it has been
cold-worked, so should hold a straight (if it didn't get munged in shipment). I'd check (sight down a length) the stock
at the local hardware emporium, you might get a pristine item with straight edges for not much outlay of cash.

simple 90 degree bend will stiffen it up too
Hate to see that bill! 10’ pieces of ground flat stock from starrett. I would want to scratch or get it dirty.

Here is a 6' straight edge for $80 lol

Yeah that would do I suppose but who’d wanna handle that. 1/4x1”-6’ would be as flimsy as twizzler hanging from my mouth. You’d need at least 3” to be sturdy still would whip. My wife has a carpet binding biz and uses straight edges a lot. Hers are all 1/4” x3”from 4’-12’ all commercial bought. Precise enough for carpet but a pain to handle the large ones. As expected if not vertical with two hands on em they bow to either direction.Here is a 6' straight edge for $80 lol

My focus is still on the straightedge more than the floor; you''ll have a tough [$$$] time finding a shop with a 10'+ plus mill, planer, or surface grinder. I'd go craigslist for a 8' plate level. A decent bar or extrusion isn't bad, just calculate rough Airy points. Your floor will never realize the difference.
