Rental Windows Replacement Cost in Atlanta Area?

[Jenny Scott]

Anyone has recommendations on windows replacement company, or installer in north Atlanta area? 

My rental windows get pretty old and the bottoms are rotted, so I am thinking about replace some of them, with the vinyl type so they won't rot. The quote I got so far is standard size, about $500 - $650 per window installed. I think that might be little high? What do you guys think? Or have any suggestions?

Thanks
Jen..
