I have also had this exact location with the oil leak. I believe the dealer fixed the HPOP seals. Stopped now showing up again very slightly. But, you is very hard to see where the oil is coming from. You may want to look up along the passenger side of the engine block for some extremely small evidence of an oil trail. It might actually look dry but could be it.
The cover you are talking about is the torque converter cover. It is very easy to take off. You can then look up in there and see if you seen the oil leak. By all means at least do this much before taking it anywhere. If it is your rear main seal there should definetly be oil there.
I wouldn't think you would need to pull the engine to replace the rear main seal. If your oil pan is rusty and leaking then you are suppose to pull the engine and therefore expensive. But if your oil pan is not leaking then just paint the rusted areas with POR-15. Don't waste your money pulling the more for a rusted oil pan. Just paint it.
As others have said I would definetly question the diagnosis.
