En efecto, <señor/señora>, hemos reunido $2063w piezas de cuero semipesado hasta ahora. Sé que es mucho pedir, pero si aún estás <dispuesto/dispuesta>, me vendría muy bien tu ayuda para reducir en buena parte mi cupo.
Yes sir, looks like we've collected many pieces of medium leather, but we need more. I can assure you that it will all be put to good use; not one piece will get wasted. I know it's a lot to ask, but if you're still willing, I could use your help in attempting to put a dent in the rest of my quota.
Golly, that sure is a lot of medium leather that you've brought round, sir! I'm gonna make sure that all of that gets put to proper use, yes indeed. With your help we'll have filled our estimation for medium leather in no time!
