Mateusz,

Is the client looking for a solution that runs somewhere on the net that 
they can make requests to, or are they looking to setup a server with 
data and a routing engine?

So I'll plug my infant and immature routing engine project:
http://sourceforge.net/projects/opengraphrouter/

Also pgRouting is an option.

The big issues in most cases will be data. Some people are doing routing 
with OpenStreetMap and pgRouting. If they want accurate (ie: navigable 
routes then they will probably need something based on Navteq or 
TeleAtlas) or if they are look at a small county or state wide area then 
they might be able to get data from the local governments like 
http://www.mass.gov/mgis/mapping.htm

Because good data is expensive and licensed, in most cases by 
transactions, it is not likely that you will find services equivalent to 
Google that are free.
