Hard to answer that since we don't know where you are. Do a Google search on the following companies: Sapsis Rigging, JR Clancy, Rose Brand, I. Weiss, and others. Use the CB search engine to look for "traveller rigging." Don't forget the backpans. Check your local yellow pages under "Wire and Rope." Befriend your local theatrical supply house (yellow pages under "theatrical equipment."
if you know how to splice a rope, and have pullies wide enough to accept the splice, I'd think that any rope can work, provided it doesn't stretch too much and is comfy on your hands

With a minimum order of 600' and a min. diameter of 5/8", that is definitely NOT the proper rope for a 9'H x 22'W traveller.
If they "just used cotton rope" before and it needs replacing, would buying a better quality of rope be more cost-effective? Possibly Iweiss:
Wire Center Rope, Cotton, 1/2" diam. White, Galvanized Wire Center, WLL = 236 lbs
Used on tracks when moving scenery or maintaining spikes.
$530.00 / Spool (1000' spools)
$0.56 / Foot
(WC500CT)
Spray-on fire retardant should not affect the life or usability of any cotton rope. Measure the floor block, live end blocks, and dead endblock; and use whatever diameter they want. Should only need about 65' of operating line. Wire-core cotton rope should be long lasting, and will not stretch over time.
