Who can build a Brick oven in Nha Trang

So, my brick oven is nearly done...at least the bricks.  I had a builder in doing the kitchen and showed him some of the on line information.  Instead of the platform to hold up the bricks, we used 3 loops of rebar, bent to the correct domed shape and covered it with a thin sheet of steel, which was wired to the rebar.  He used the solid half bricks...my suggestion, for thermal mass.  They were laid with the thin side facing the form, to better follow the curve....2 layers.  He also rounded the back and curved it up to the top....his idea.  The only area where we differed meaningfully in, was placement of the chimney.  He thought that it should go at the back, but it needs to be at the front....fire in the back, food in the front and hot gasses forced forward to evenly heat everything.  He parged the outside shell, but left face bare brick, for that rustic look.  All I have left is to get a metal shop to fabricate a door and chimney.  If you private message me your e mail, I can send a photo,
