Structural Design of Cranked Steel Beam

Urgent!

Cranked Steel Beam design and calculations required for a house extension. I need this completed today or before Monday 21st July at 7am (GMT UK time).

See CAD drawing attached- the drawings within the red boxes have the relevant current details.

Main considerations:
- Beam to follow the pitch of the roof.
- Beam to be fixed to a horizontal beam that is being installed directly above a new window.
- New window bridges an existing 230mm solid wall and the new 310mm cavity wall so the beam will need to be designed to work with both these structures.
- Please include an idea of how the beam will be fixed together, fixed to the beam above the window and also how the wallplate detail will work with a padstone etc.
- Draft size of 203x203mm has been noted but this isnt the design- please propose the best solution.
