I can give an example of my negotiations with a possible customer from La Coruna. He wanted to order for himself a model of the French corvette, which sank off the coast of this city. He saw my work, we discussed with him the reconstruction of this ship (there are no drawings of this corvette in the archives). Then he demonstrated his foundations, from which he builds an understanding of the value of this work. He himself once collected kits. And this circumstance could not allow him to adequately see what really stands behind my work. He evaluated himself. And its ceiling in this assessment is 2500 euros.
