Cad designer needed to make a cad file of small product

Description: I'm launching a novelty golf product and need a manufacturing-ready 3D CAD file created from a concept render and written spec. The product: A golf divot repair tool shaped like a stylized hand/fist with the middle finger extended (humorous novelty item). It includes a bottle-opener head at the top and two divot-repair prongs at the base. In the center of the handle, there's a small circular magnetic ball marker insert (separate piece, magnetically removable) bearing our logo. Two pieces needed: The main tool body (hand/fist + bottle opener + divot prongs) A small circular magnetic ball marker insert (~20–25mm diameter) that seats into a recess in the handle Requirements: Final files in both .STEP and .STEP and .STL formats Designed for zinc alloy die casting (correct draft angles, minimum 2mm wall thickness) Overall tool length ~90–100mm Recess/seat designed for a magnet or steel disc insert so the marker piece sits flush and is held magnetically Clean, manufacturable surfaces — no overly complex undercuts 4+ rendered preview images (front, back, side, 3/4 view) of the assembled product What I'll provide: A reference concept image A detailed written design brief with dimensions and style notes Budget: $150–350 depending on experience, with 2 rounds of revisions included. Ideal freelancer: Has experience designing products for die casting or injection molding (not just rendering/visualization work). Portfolio should include real manufactured products, not just architectural or animation projects. Please share relevant past work in your proposal, and confirm you can deliver both .STEP and .STL formats.
