We are installing new stacking doors and new brick boxing required

We are switching out a window and getting a new stacking door installed but our house has a weird design. We need the corner section to be boxed out with existing bricks to be re-positioned so both sides are flush. Purple pen is where boxing is needed. Yellow pen shows brick that will be removed and can be re-used. The red brick will also need removing and replacing. Your ideas of how we can best do this and a quote is welcomed.
