c compiler imo needes something like about form few months to about year
of coding of 1 person probably if he is somewhat experienced and healthy
so the cost i would probably estimate as prbably something like from 
100k maybe 200k maybe 300 k dollars/euros depending on things
(raw cost imo could be more like 100-150k maybe but the risk/taxes etc
could increase it, on the other thing there are people probably able to 
do things cheap)
  (im not a merchant so i dont know but something as this estimation imo)
