Let's see: 6i24 = $139 7i33 = $69 7i47 = $69 7i44 = $69 7i77 = $119 (48 outputs, not really for buttons?) 7i70 = $79 (48 inputs not really for Relays) ========= $544
Perhaps take a step back and make a list of how many inputs and outputs you expect to need. Wouldn't a 7i78+5i25 Plug-n-go kit for $158 work just as well?
