I’m normally involved in the Tech bits of Dry Leasing – so the following is from dim and distant memory of the last time I was involved in a Wet one
Wet leasing is conducted by a few airlines as their core business and by some as a way of keeping the planes working during their quite periods – thus if your lucky you may find someone who’s real target is just to make “a little” but keep their crews and planes working – for this (and market forces) Lease Rentals can vary quite a bit.
You can expect a Monthly fee which includes X hours Y Cycles – do less than X or Y and often it’s your problem (no refund) – do more than X and there will be a hourly rate.
You may get a hourly / cyclic rate for the LG / Engines / Airframe as an additional fee to pay per hour – or it may be inc in the monthly – this is to cover the “loss of life” on these items – if it’s included in the monthly fee the fee will LOOK higher than if it isn’t – so care is need to add ALL costs up to get the REAL rate.
The lease will include provisions for Crew / Handling etc etc.
Many (Most) Lessors won’t talk to you seriously unless your “end user” or you have signed mandate from end user – if it’s the latter you can expect 90% of the Lessors to try and deal direct with them as soon as they find out who they are.
Speednews
http://www.speednews.com/listings/jetindex.html have a few ad’s for Wet A320’s – if you have a reason for asking – like Uni project some will give you “clues” (ballpark figures) if you call / mail them.
If you are “end user” or have a mandate – have someone conversant with Leases read it – even a simply suitably placed "and/or" instead of "and" can make a MAJOR difference to your cost exposure.
