Twitter Connect (oauth)

Dear all

I need a Twitter Connect addon for EE2 with the following functionality:

• Registration via Twitter (EE username => Twitter ID, copy of Twitter username, Twitter Name and Twitter Profile Picture URL to EE)

• Login via Twitter (and updating at the same time Twitter Username, Twitter Name, Twitter Profile Picture URL)

I know that Socialee can do the same, but the Janrain service is really expensive with more than 5000 users.

I would be happy to find a developper who is able to create such an addon (for money, of course).

Thank you very much, MISC
