Handyman/Carpenter needed to fix water leaking in under backdoor and repair damaged flooring

[MikeW1]

We've started having water leak in under the threshold of our back door, with the water coming up through the wooden flooring near the backdoor. This happens whenever there is heavy rain, and we think it has started due to us paving outside the back door and raising the level of the ground such that water can get in. Will require someone to look at and potentially replace (and seal) the threshold for the back door, likely add a rain deflector, and replace the wooden flooring that has been affected (we have spares). Can anyone recommend someone for this type of job?

Thanks!
