TRIGGER LIGHT CUES WITH SOUND EFFECTS SIMULTANEOUSLY

Hi all
i have this project for a permanent installation and the main request is a dmx desk that you can programme light cues that can also trigger special sound effects.
They ask for a turn key solution , so that means i have to propose also the device they have to use for playing these audio tracks and how to enter the timecode into the desk and connect a light cue with the specific audio track.
I think i need to use one LTC WIDGET and depends on the budget from HOG4PC to ROADHOG4.
but i dont know the rest configuration and how actually this must be set up, and the procedure to get the prefered result.
if anyone has done something like that before i would really apreciate any info that could give me some help.
Thanks!!!
