Hello, I will not sign a NDA neither any document for less than 10k. Anyways if you ask users here to sign a custom NDA I am not sure if your NDA will be valid neither your business , because you are violating the terms of this site from the beginning, asking users personal data and attempting to do business with users with different terms of this site. This site offers an easy mechanism to do that you should check out. If you can find a way to avoid NDA or similar ping me and I will try to look a solution for your case. I worked in black list phones detection , including wsp , but it seems you want to block a call and I am not sure if is possible on the normal devices, ping me and maybe I can research a bit if you are ok . Cheers Gonzalo
