Looking to pay someone to create a large part

Fixed that problem they used breadboardbreadboard (rather than breadboard) for the layer ID fixing that looks to have fixed my breadboard connector problem. A question: I assume switches b0 to b3 are led push buttons? With 4 of the connectors the button contact and the other 4 the led
(in which case, which connector bank is switches and which is led?) I think everything else is pretty much self evident.
