Custom Joomla and Jomsocial extension - Phone Verification Component

Project Description: I have a site that is built on Joomla 2.5 and Jomsocial Latest I need these things added to it: 1) Require a new user to verify their mobile phone number (integrate with a third-party SMS servicee API, I will provide the credentials) 2) Number should be linked to the account. Only one account per number should be allowed. 3) Display the number in their Jomsocial profile with most digits replaced by asteriks. 4) Allow changing the number by verifying the new one 5) Require SMS-verification for password recovery. I can provide a more detailed description on request. I would like to hire someone with experience in building extensions for Joomla. I need this to be a proper extension that can be installed/uninstalled via the Joomla backend. I would really like to find an experienced programmer who would be interested in making further alterations to the site in the future.
