3D Modeler for Art Installation

I am designing/building a large surfboard fin farmed with EMT steel pipe and clad in polished aluminum, resembling an Airstream trailer for an outdoor art installation. I am looking for a 3D modeler to develop a relatively simple model based on my drawings so I can fabricate the bent sections of pipe, etc. The installation features two main connected sections: the "Base," (13' x 4') and the "Fin Top" (2' x 16' after factoring in the additional height of the Base).

I will need two final versions of the model: one full size, and one scaled down to a total height of 6' for my prototype.

This will certainly take a few iterations, as I need to figure out whether I will integrate a daybed into the top of the base for people to sit in.

Thank you so much! This is going to be an amazing project - I'm so excited. :-)
