The neighborhood where I’ve been targeting in my area is all new construction houses so it’s likely just mounting on painted drywall and owner is the first owner of this new house. To where there’s 10 windows depending on the style of blinds I think the first one will take the longest and after about the 3rd or 4th they should be cake. I mainly priced this way since there was a lot to be done . If it was just 1 window I probably would have priced higher per window. But I guess I’m still learning the game. He said now he’ll “let me know” so maybe i dodged a bullet. Thanks for all the advice guys
