Ajax, Facebook, and One Page Login test and debug, Password not match etc -- 2

1. Currently the Ajax login is not working properly (so disabled), the onepage checkout keeps saying Password not matching. And I need a systematic test on all browsers (esp explore) and platforms to make sure there are absolutely no issues with customers login. 2. I also need magento logout time extended, and customers to be auto logged into Magneto when they visit the site. Like ebay etc. 3. I also need the Facebook module tested to make sure that is also 100%. The site is a live site. But these fixes should be very easy for a professional magento expert. I have seen many discussions on Stack exchange about this password not matching problem. I need to reiterate I need 100% functionality and test of these things across all major browsers I cannot lose customers because people cannot create an account. [login to view URL] NO blind Bids, no discussion of work you did that is not related to what I have written. Pitches that DO NOT discuss my issues will also be ignored. I am not going to look at all the unrelated websites as proof of work, ONLY what proposal you can make for this specific product. I need someone who can give a timeframe and report on what they plan to do.
