Contacting Yvelines Numériques / Contacter Yvelines Numériques

Today I wrote an e-mail to Yvelines Numériques to ask about splicing into their fiber in our village. I decided to send the letter off in my bad French rather than wait to have someone go through it and perfect it. That may have been a mistake but I figure I'd rather get as much information as quickly as possible. I've asked them how much it will cost to splice in and then how much I'll need to pay for connectivity per month to reach one of the Internet exchanges in Paris. I specifically asked about the prices to reach POUIX or PARIX.
