RME fireface 800 is amazing and built like a tank. Would def get the job done for you. I used one in a post sound studio and the onboard preamps are very nice and you can get it even modified by Black Lion Audio if need be.

I have 2 Portabrace bags if you want to use both of mines to test out. I have the Large and Extra large type audio organizer bags(can't remember exact model).
