Chrome extension - Automate actions

Hi, I'm looking for a freelance/team who have already coded several Chrome extensions and Firefox and can prove it. I need an extension which will be distributed as SAAS for users: So you have to know how to manage the security of the login, grant access and back office to manage the licences/users. (Plugin which handle everything are available on codecanyon). There is several features needed, but for now I would like the extension visit all the results of a google research, scrap some data of the pages, and put them on the dashboard. I have several open-source extension which already handle some part of what I want. The goal would be to setup everything together and create what is missing. - I'm looking for a long-term business. - I need to see your previous work. - I have experience with Freelancer and I know the bidding price doesn't mean anything. We will discuss it later when all the project is clear. The most important part is your experience and your ability to manage what I want. Please, start your message with the word "Chrome" so I'm sure you've read my project and please, give me anything to show me your previous work. All the User management part is really important, so you have to know how to handle everything and it's better if you have example of extension you've made which include it. Don't lose your time if you are not 100% sure you can handle it.
