Android WIFI auto switching and related logic -- 2

I have a partially completed SSH app with that sent pre-configured commands to a router running Openwrt. I need you to help me code the following within my current app and possibly other associated portions. 1) Construct a list of WIFI access point as reported by Openwrt via SSH command 2) When user select the AP listed and entered the password/key, the app will switch its WIFI to test the password against the selected AP. If password is correct, it will return to the original network/AP, re-establish SSH connection and sent commands to instruct the Openwrt router to switch to client mode and connect to that Access Point. If password is incorrect, it will will return to the original network/AP, re-establish SSH connection and ask the user to re-enter the password because it is incorrect. Additional information including current app will ONLY be provided to those who demonstrate competency. ------ Prior experience in using Openwrt router firmware via SSH preferred. Specific SSH commands used will be discussed and tested before you implement it. Preference will be given to those who are competent and experienced in uPNP, Airplay and streaming multimedia. I have high expectations of you and do not bother bidding if you are not competent or have time to make this work.. If you pull this off and do well, I will have additional work for you.
