Architect for residential building in the Cincinnati area

[Edo Y.]

Hello.

We have a residential building of 3 stories and 8 units in Cincinnati. The basement level is partially finished and we would like to add 2-3 units in there. We would like to do it all legally with plans approved by the town.

Any recommendations for an architect / company that can assist us with this project? 

Also what would be a reasonable price range for this type of project? Each unit would be 400-500 sqft.
