Why did you make two threads on this?
This is like the 10th question I’ve seen in the forum recently about background removal gigs. As I’ve written many, many times in response, you don’t get orders because this work is something a free automated tool can do (if there are differences in your work and value, you aren’t expressing them and haven’t noted if there’s even a demand for that) and also because you have a competition of thousands of people selling background removal.
Don’t create gigs unless you know your market and your competition. That’s the quickest way to fail.
