you are wise to have it cleaned before shipping and storage. Wrapping storage and cleaning should be approximately $300 - 400 USD at most. make sure you take photos of the rug after cleaning & before storage just so you have them. The wash tag on the carpet shows information as to who it was sold through. You will want photos of this before cleaning - I know someone who has documentation of what some of the abbreviations stand for, so you can probably find out who imported the carpet.
Persian Kerman semi antique rug - most people won't know what the floating border means. 60-70 years is just about right so that makes it a semi-antique. Accurate age id is important as post 1960 these rugs became heavily commercialized. Knot density is not particularly important, but it is good to know.
