Hi, I think SprutCAM will do exactly what you want it to do here but it's a little under 3k. If you do find anything with 3d machining and 4th axis indexing under that price, let me know! If you have your heart set on the 1k budget, you might be stuck with BobCAM (I fiddled with their demo for days and never got a toolpath - with Sprut you will make toolpaths in minutes without even reading the manual). Sprut have a full 30 day trial which will allow you to post code and see what the parts come out like. I actually used my 30 day trial to generate toolpaths for a low volume production part - once I had made enough money on that part (took about 6 months) I purchased the full version. Cheeky way of doing it but SprutCAM had paid for itself before I even purchased it.
