I have a question about brokering a load of scrap,

I have a connection to get 20-30 tons of scrap (which is currently selling for $.20/pound), this connection is currently producing this amount on a monthly basis.

I have found (via this forum) a buyer for this scrap that in the past nobody has offered to purchase.

The problem is how much should I pay the producer for the scrap? They do not have this connection of the buyer. Another problem I am seeing is the person with the scrap works for a company and is a family member, would this be a conflict of interest if they sold it to me for $.10 a pound?

Thoughts?

Thanks!
