Hi Felicia, 1) yes. 2) ID can revise quote. can negotiate price with ID. but electrical items are usually charged by per item. 3) can. but you may have to forego any deposits that you paid previously / ID may charge you for the 3D drawings shown to you. If you don't mind, I can recommend a designer to you. Steven @ 8777 7233. He had renovated my house, recommended to my friend and she's satisfied with the work done. And now my friend's neighbour also approaches him for his house renovation. FYI, he's always readily available to provide you with advice and recommendations.
