Combining Two Units in Multi-Family Into One

[Anthony H.]

Hello,

I'm looking for a contractor who has experience with the situation below -

I have a multi-family property with four units. I'm looking to combine two units (3rd and 4th floor) into a duplex up. 
4th floor has a kitchen that will need to be rehabbed/repurposed into a master bedroom by combining it with an existing bedroom space. 
These are the current floor plans for each floor -

Please reach out to me if you have had experience doing this and can provide me with an estimate (costs + timeline).

Thank you,

Anthony
