Door/ Door frame to be replaced

Looking for someone to replace the door frame and door to the upstairs bedroom terrace/ balcony. Water damaged has caused the door not to open and close properly. Will need this person to also determine the reason for the water leakage to prevent it from happening again. Want this person to also check the box gutter system on the roof to make sure it is draining properly off the roof. Once the door is replaced this person is to install/ repair missing wall panels as shown in pictures below.
