HI
Dont take this the wrong way, but in your 1st post you say youre not an audio guy?
It would seem to me that a job that is over many days, and out of your country must be “reasonably important”
If it is important (either to you or your client) then do consider wether you really have enough
time
brainpower
manpower
ability
confidence
spare attention to fix all the stuff that will go wrong
AND shoot the pictures, light it, media manage it, and get it ALL right 1st time.
You might be able to do it all, but the fact youre asking the question at all suggests to me that this is outside your comfort zone.
If so, do consider hiring a professional.
I doubt your client will be terribly understanding if you have problems, the audio is bad in places, then you say you were overstretched. If youre worried, recognise that now and hire in the necessary staffing. Youll get more respect for taking the right line even if it does cost a bit???
It doesnt seem like the sort of thing that can be recreated easily?
Just my thoughts.
