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

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 and platforms to make sure there are absolutely no issues with customers using ajax and one page to login or reg to the site. I also need magento logout time extended, and customers to be auto logged into Magneto when they visit the site. Like ebay etc. 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.

New bidders will be ignored. Pitches that DO NOT discuss my issues will also be ignored. I am not going to look at all the unrelated websites you made in the last 10 years. I need someone who can give a timeframe and report on what they plan to do. If you miss the time frame I will get someone else. I am also not doing any milestone unless 100% confident the bidder knows what they doing.
