Be prepared for an enormous waste of time.
I had built a beam element FEA model of a stiffened ladder frame for a 55 Tbird. That is, I has specified the section sizes, and the hardpoints of the end of each straight section etc.
I needed someone to turn it into a CAD model suitable for meshing, but since I was flat chat doing my day job decided to sub it out over the internet. The quotes I got back were mostly from India.
It rapidly became apparent that at the bottom end they were just kids who had been 'taught' a CAD package, who I would then have to teach how to model, and at the top end they still had no bloody clue about vehicle or component design either, and wanted 40 hours. I did it myself in two evenings, but had the advantage that I knew what I wanted and understood the job exactly in advance.
The problems with remote working are not insuperable, I have worked on many design projects with Germany and Japan and Thailand and the UK, the problems with language are trickier, but we work with China all the time, admittedly with some very good bilingual people who are paid at the same rate as we are. I think overall the cost save from outsourcing CAD to a cheap place is marginal, at least for Australia and the USA, and I specifically think there are cultural problems with trying to do it with Indian staff. You need to find someone who knows your industry.
In the past SAAB and Volvo took enormous numbers of CAD guys from the UK, they can't all have gone home?
