Social login product for vBulletin 3

I need a product developed for vBulletin forum software version 3.8.x I would like users to be able to login and register with google, twitter,and facebook. While existing users can link all 3 of their accounts to their existing account. This product would consist of files I upload to my forum, so it does not rely on anything other than my site, google, twitter and facebook. The main focus (login/register) I really want is google, but would prefer all 3. I am a developer for vBulletin 3, this is just a little beyond my experience. I know to the right developer this is an easy task, integrating a user system with an existing user system. If any assistance is needed I am very experienced with vBulletin, and I developing products for it. Just a user OAuth login /register system is beyond my skill set. If a forum with vBulletin installed is needed I can provide since vBulletin is not free software. I need someone who can get this done reasonably priced and with no hiccups, someone who knows what they are doing, and can guarantee the product I am looking for. So if you're experienced with vBulletin and would like to do this for me make a bid and describe you skills, thank you.
