Sounds like you did answer it yourself, which is awesome. I actually like your approach of aggregating and sending it out to the suppliers. You could send it to all of them and tell them they have a limited time to respond, and then creating a ranking system based on who is best at meeting customer demands. That way, you have a preferred list that gets more business by virtue of the fact that they're better. That's fair to all the suppliers, gives them something to work towards, and makes your customers happy.
