I would recommend that you try to track down the offending gasket or seal. The easiest way is to clean up the mess by pressure washing or steam cleaning. Add some UV dye to the transmission oil, and when the leak starts to show, you can usually trace it to the source with a black light. You can get the dye and blacklight at most parts stores.
It is difficult (if not impossible) to quote prices on this forum. Labor rates vary by region, and different shops have different pricing methods.
Either way, if you have a pan gasket or axle seal leaking, this is a relatively inexpensive repair. If you have a converter seal or chain cover gasket leaking, it would require removal of the transmission. So far, I have never seen a failed converter seal in this type unit - or a major gasket for that matter. Most common leaks are at the bottom pan or axle seals.
In many cases, someone has driven onto a curb stopper at some point and warped the oil pan. I suggest that you check some of the easy repairs first. You stand to save a lot of money!
