Transmission Repair Needed in Phoenix

First post to this forum!  I am the proud new owner of a 1998 Sport Nautique in very good condition but has revealed a significant transmission fluid leak on it's first use since purchasing it.  I got such a sweet deal on the boat I am not even phased by the need for repair.  I'm looking for a recommendations on a reputable shop that specializes in transmission rebuilds in the Phoenix area.  I am comfortable with removing and delivering the unit then reinstalling it myself but I feel the actual rebuild should be left to a professional mechanic.

I've already found a wealth of knowledge on this forum and I feel like I've only scratched the surface!

Thanks in advance.

The leak seems to be coming from the (front?) of the gearbox where it mounts to the bell housing.  So based on some searching here on the forum, that seems to indicate a pump seal.  The previous owner since 2005 believes the trans has never been rebuilt so I'd like to have all seals and gaskets replaced.  I don't think the case or hard parts are damaged.

Thanks for the response!
