What you ask for is something every haulage company is doing those days. (at least in areas where mobile network is dense enough)

There might be legal problems because this could be called spying under some jurisdications

Works only if the mobile has some way to post the coordinates to you. -> Internet -> SMS

lon /lat on google is as easy as https://maps.google.com/maps?ll=44.873889,20.651944. On can automate that (at least I have heard of, never done) so that one can see every traced thing on a map moving.

I'm not shure if google allows that on a business level. I know that google limits the "download" of map parts for a day. So possibly you have to spend some money.

Consider OSM and a donation?

Check app market for apps that can phone (iow share) there co, there is a existing market. I do not use it but I think OSMand an Android App can share COs, and other can do that to. OSM is available on the rotten fruit to, no idea for M$ mobiles.
