Security testing task for a website


Job Description

I have developed a web based application on Ruby on Rails and want to get security testing of the app done. This is kind of social networking application. Some of the essential items that I wish to get tested are -
Vulnerability scanning -
Penetration testing -
Posture Assessment

I am looking for proposal with regards to how you would achieve this task and execute this project. Though I have some tools like Backtrack in mind, but if you are comfortable with other tools we can go for those as well. Also while sending me a proposal, please send me some info regarding the past security testing work that you have done and the result reports that you share after the test excution process.

To avoid spams, please add 'Security Tester 2012' as headline.
