Opening the rear wall for a deck

We are planning to buy our first house (3-story, 16.6ft wide brick) and – as part of the renovations – install a rear deck.

Our idea is to open up the rear wall of the parlor floor to bring light in and give the kitchen an airy feel. The opening would be at least as large as required to fully include both windows, about 11×8 ft (see red lines in the picture). Ideally, all the way up to the ceiling. We would then put in some industrial style (metal+glass) folding doors that we saw at a cocktail bar in red hook and fell in love with. Then install a 16x7ft deck (iron frame, non-combustible wood paneling).

Now my question: If you have done similar before (opening up a wall and install a deck), how much did it cost you to do all the work (take out the wall, install the beam, clean up the masonry, install the doors, etc)? Any complications or issues, words of advice?
As you can see, the heating pipes and radiator are in the way as well and would have to be moved into the corner (we are re-doing the floors in this and the upper floor anyway).

We are on a tight budget and – since we have never owned a house before – need a bit of a reality shock in terms of prices and complications. To better understand what we get ourselves into when buying this house.

Thanks a lot in advance for your advice!
