$1000 is way too much to spend unless you have that kind of money to throw out the window.
My experience: 6 months ago, my wife (RN for 22 years) and I (experienced turkey and chicken carver) put a child's sock over my favorite chicken's head and neck in order to operate and clear out her impacted crop. Scalpel, needle and thread, super glue, the only thing that I would change next time would be better thread material. Everything went very smooth, our chicken hardly moved at all. We didn't know what we were doing and she lives on today.
Why don't you ask the vet to have the vet tech put a sock on the chicken and hold it down while the vet does the surgery? $100-150 should be enough for a 10-15 minute cut and suture.
