Not sure who handles Synergy, can you send a sales person down to qualify the lead?
To my understanding there are price concern for this customer in this region, that's why they are not buying much from us. So I would have doubt these would convert to leads.
Can you understand the sales cycle of this customer and get back to me? Some of these customer only want to get samples to build their library. If that's the case I would get them to buy the samples, we can provide discounts for those.
