I realise that this might be horribly inefficient, but apart from that, is there any reason I couldn't just run the first query and populate the array (which already works, as tested previously) then run the subsequent query, and for each iteration, while loop through the array and populate the array for client IDs that match?

I don't understand how to add the column to the array, but other than that, it seems the simplest way of achieving what I need. Yes it means quite a bit of extra computation, but this query will at most be generating a couple hundred lines (i.e. clients), and will complete in no time regardless.
