between 1500 and 2000 would be what I would ask for that piece, based upon your material selections of birch and poplar which are probably the most prolific in use for furniture, due to the rapid growth and ease of milling. I see the labor at about 25-35 hours due to the design and finish... so I think that is a good ball park... now if you were to do most of the solid pieces in oak or cherry that price could go up to 25-3000 bucks... those woods are fairly easy to get so you wouldn't be outlaying much more cash up front for the materials and you could have more traditional finishes to appeal to more people. all in all from what I see it's very good work.
