I would suggest putting the Opsis and such in a half rack case - like this

$220 usd

6u =
2 mic receivers,
2u draw fro mics and short cables


I have a full sized 4u case that I used once or twice, and I found it
annoyingly large given I didn't really need that much space.

ps - my understanding of "front of house" is the spot in the audience area
where the mixers are.  we can debate what meaning of house and its
origination, or just try to figure out how to communicate with venue staff.
