How can we advise our ECA's on which products to sell?
I think that is probably not the right question. Truth be told, I don't believe it is in our scope of things to suggest to the ECA what THEY should sell and for how much. We can be a sounding board when they are talking about their prices or their products.
I don't think it is our place to tell them what they should do; however, if we are asked, we should have done enough research to be able to answer intelligently.
