Revision of a House Project

Hello, I have an unfinished house project, I had a disagreement with the architect so I've decided to find someone to finish the unfinished bussiness. I've attached a pdf file of the project, the .dwg file may slightly differ from the project file I've send but more or less it's 95% same. Things to know: I'll be sharing the .dwg file with the one who will work on the project. What bothers me with the below project is : 1- as you will notice when looked to the pdf the second floor is lagging back a bit compared to the base floor. this causes columns to block the view of the right most bedroom. 2- I want the chimney to be two sided(common) for both sofas. 3- I want to relocate the entrance of the storage room in the kitchen 4- relocate the position of a window in the kitchen above are the list of changes I want it to be done. along with static calculations. I don't know about the market prices so please bid accordingly. I also kindly ask for 3D modelling price when the above changes are done. If you have any questions please ask, Thank you.
