Add membership subscription to my web app

I installed a Facebook web application script for list building on my server.

The web application script can be used to build lists through Facebook.

I want it to be converted into a membership program where different users can sign up, login to his or her account on my server, and use the web application individually to build lists through Facebook.

The completed work must be responsive.

Apply if you can do it and answer the following question in your cover letter:

1. Have you done such work before?

2. How many days will it take you to complete and deliver the work?

3. What is the minimum amount you can do it?

4. How would you handle security to make it hard for hackers to break into it for free use?

5. Describe how you will do it from the start to finish to achieve the purpose.
