Ha! I was thinking, “find a freelance SW designer.”
Otherwise, bite the bullet and buy your own license ($3-5k). You could also use other software, like Rhino ($800) or see if AutoCAD is still available for free. Sure, it isn’t sexy, but the result is the same.
As a consultant, the incremental work I was able to bill using software I bought allowed me to pay it off in the first two months I owned it. Something to think about…
