Ooh - this is good to know! I'm not OP but we also need to replace 9 windows on our rowhouse and they are one of the companies we called for an estimate.
OP - my suggestion is get on Angie's List. It will really help you get a sense of the price, the process, a company's customer service record, etc. PP's quoting random figures like "$300/window" are not telling you the whole story. You have to pay for the window itself but you have to consider installation. If you need any reframing done that will be even more. I've seen a range of prices on Angie's List that runs from about $5-8K for the number of windows you and I need depending upon the installation requirements.
Good luck!
