ETC Sensor/dimmer Rack 48/96 w/48 2.4k dimmer rack touring

Hi I'm looking to purchase a used ETC Sensor 48 Channel touring dimmer rack,  The rack only has stagepin inputs and I would like to add the soacpex inputs to the rack if I purchase it.   Could you give

me a rough idea of what it would cost to purchase the socapex input panel and have a certified tech install it?   I'm in the San Francisco Bay Area.

Thanks,

Johhn
