I tried with freelancer, got to compete with Indians and others who are happy to work for a few dollars an hour. I put in a few bids and wasted quite a bit of time creating models and sending pictures of my models and getting nothing but others looking at my designs. Don't bother with freelancer unless you want to work for nothing.
The grabcad group of freelancers is just as useless, I have been looking at it for years, sent a few emails and got nothing.
