Those sound terrible.
You have to consider that professionals will be using this terminology. CEOs of companies are not going to be going around and saying "Our new product should cost 30 en-bees".
And yet they are perfectly happy to say that their product should cost 30 "doll-ors", 30 "you-rows", or 30 "pay-soes"?
Yes.
dol·lar
Origin
from early Flemish or Low German daler, from German T(h)aler, short for Joachimsthaler, a coin from the silver mine of Joachimsthal (Joachim's valley), now Jáchymov in the Czech Republic. The term was later applied to a coin used in the Spanish American colonies, which was also widely used in the British North American colonies at the time of the American Revolution, hence adopted as the name of the US monetary unit in the late 18th century
en·bee
Origin
a term made up by Internet user DannyHamilton that has no real meaning and no real history
