what to do with bees?

I live in a suburban area and I have a swarm that has set up housekeeping 
in an low hanging area of my roof.  They are apparently very 
domesticated, they are not overagressive, I can stand within 3 feet of 
where they are entering and exiting, and they will ignore me.  

Of course I don't want them on my property.  I called a couple of 
beekeepers and they said they would be glad to come and kill them -- for 
$250.  I told them I can do that for free.  I'm trying to be 
environmentally friendly on this I know that bees pollinate, etc, etc and 
don't really want to kill them.  

But what else can I do?  Killing them out may be my only option since I'm 
a good 15 miles from really open country. If I drive them off, they'll 
just take up residence in somebody else's home.
