Buying used greenhouse frames

[PD321]

How would I price old commercial greenhouse frames? They range in sizes and are galvanized metal and/or aluminum. Would have to be dismanteled ourselves. New Jersey location.

How much work will be involved in dismantling them?
Aluminium frames oxidise, and galvanised frame fixings tend to rust.
If it is frame only you then have the cost to re-cover.
I reckon I would seriously consider offering to clear the ground by removing them, as a favour but if this cannot be considered it then depends on how much you think you will save. You could also check out any auction sites apart from the obvious to see if you can make any comparisons.
