Concrete walkway replacement

Hi,

I would like to know how much would it cost to have a concrete walkway redone.

There is a metal fire escape staircase above it and one of the support beams has caused some of the concrete to crack and separate from the post.

Size is about 35ft x 6 ft (approx 200sq ft)

What would it approximately cost to redo the walkway and secure all 3 posts.

The stairway and door that leads to the walkway is needed to be used, so sufficient support for the stairway and walkway is needed for the side door as well.

Please advise what the per sq ft or meter pricing is.

Thanks.
