Solder, I assume, not crimp, since you'd need the tooling
Male is more common on cables. Are you sure your friend needs a female
jack on the cable?
Pasternack has them for about $5-6 PE4008 for the male
PE4115, PE4120 are female, latter for bulkhead mounting. They're about
$10 each for the 4115. There are also flange mounts.

Most solder on connectors are going to be gold plated (so the solder
sticks), not nickel or stainless steel.

Since it's semirigid cable, just solder to a standard flange mount
connector. Maybe a few mm of center conductor exposed and soldered to
the center conductor of the connector, then a thin layer of tape, then
some copper foil to bring the shield around?
How critical is shielding, loss, or match? What works at 10 MHz may
not work at 18GHz.
