I am looking for quality people in Houston, TX to build a centrifugal fan using airfoil blades which moves air out radially (in all directions) on an electric engine with minimal weight (of the machine assembly).
I am also interested in instructions on how to construct a quality product myself without expensive tools (even with toothpicks and straws, tape and glue, if it accomplishes the mission).

Dust and dirt won't be a problem. I would love to farm out the technical works, but I don't have any quality CAD software. I've thought to do it by hand on graph paper, but the airfoil shape (essential for efficiency) and the 3D nature seem to bring complexities which require serious CAD programs. But I don't know who to farm to or which CAD program is best for the type of designs that I am considering (complex cylindrical geometry).

Well thats really several questions. Any fab shop with laser or plasma cutting equipment and some machine shop capablility can fabricate a centrifugal blower wheel. We've build several using stainless steel. But not with Air foil blades, which are only good for clean air, if any dust or dirt is in the air stream I'd recommend flat rather than air foil blades.
As for the second part, theres never been a time when it was easier to produce a high quality product without a lot of expensive tooling. Advances in computer aided design and CNC machining have made it possible to produce precision parts in small quantities.
The company where I work produces one of kind special machines and what components we can't buy off the shelf we can fabricate for in most cases ourselves. But I could farm out all of the welding and machine work and only bolt the assemblies together will nothing but hand tools.
One of our competitors in Florida builds food processing equipment. He farms out all of the components which require machining or welding. He assembles his equipment with a wrench. To do that would require accurate component drawings and proper tolerances. Which if you have a good CAD system shouldn't be a problem.

I think you should go with Integra Manufacturing and Engineering if they are still around. They seemed to be having a bit of trouble a couple of years ago so who knows if they went under but they do/did awesome work.

Is this not an off-the-shelf squirrel cage?
