Your description sound awfully close to mine when I sold my doors a while back.
I purchased a complete pair of PW/PL doors in similar condition for $400 plus shipping recently, and I believe they came from RI! The guy who sold me the doors crated them in one crate and the total was like $200 or so. You could do them in one crate, just build a divider in the middle and rest the second door on it...it will saveboth you and the seller some cash and also save time since you will only need to build one box instead of two.
I then used his crate and sold my doors a couple weeks later and made a little money to boot (but my doors were in better condition).
Let me know if you need any help as far as shipping them and what to look out for.
