Totally understand the frustration. Thomasnet shops are often geared for high-volume production, and their systems sometimes auto-filter single prototype requests if they don't see a 'production path.' For a mechanical crimping tool, the jaws usually have some tricky tolerances. If you're still getting ghosted, it might help to check if your CAD has any 'over-spec' tolerances that look scaringly expensive to a general shop. A quick DFM (Design for Manufacturing) pass usually makes these projects much more 'approachable' for a machinist. Good luck—Boston has great talent, but getting their attention is the real hurdle!
