I have a Verizon Fios install (trench) Question..?

Hello. I received mail from verizon stating that I had verizon fios in my "area" I went online, put in my address and phone number to check availablity and it said they were available. so I spoke with a verizon sales rep, he signed me up for install on the 12th of december.. Now, Here's the deal... My current utilities are burried. and from the main street to my house is a good 150 feet or so. When I spoke with the sales rep he said it shouldn't be a problem, they wont charge me for any of the wiring, the installation is 100% free.. I'm just wondering if they will be able to dig a trench that long to give me fios access.. and how long does it usually take for them to dig a trench that long? Do they use heavy machinery that quickly moves along or is it going to be some dude with a shovel?

I brought it up to another tech and she just had a kind of *duh it looks like its available* answer.

Any input would help. is there anyone out there that was in the same situation as I am?
