Google map routing

All,

We have a new delivery territory we'll be adding in a month or 2. These
are defined delivery locations (260 of them) that will not change. We need
to set them up on delivery routes.

I have plotted all of them on google maps for the transportation manager.
I've been using Mr. Google to try to figure out a way to automatically
calculate some delivery routes. This is a one-time deal as once the routes
are set up, they will not generally change, just some minor tweaking.

Not really finding anything free. Not opposed to spending a little money,
if something was worth it. There's one, www.routific.com, that seems like
it might fit the bill. They even have a 7-day free trial, which we would
probably get it done in that time, but that just doesn't seem right.

Just curious if anyone has any experience with software in this area.
Thanks.
