Custom Redirection WP Plugin

Need a plugin that when activated redirects all visitors to a new domain URL, and allows search engine bots to contiune to crawl/index the old one. Example: [login to view URL] is looked up either by typing in the URL, or by a referrer (search engine, backlink, etc). If this is a real visitor browsing (passed seacrch engine check), they are sent to [login to view URL] (this needs to have an input box in the plugin options). If it is a bot, then the bot continues browsing/indexing [login to view URL] Only Search engine bots I care about are: Google + variations (Google image, [login to view URL]), Yahoo + variations, Bing + variations, and Answers + variations. The rest I can deal with with [login to view URL] There needs to be an input box where I can input IP addresses so I can access the site. I'd also like an option to be able to enter in URLs that will remain and not be redirected (login page, RSS feed, etc) Needs to be an accurate counter that counts the amount of visitors that have been redirected. See: [login to view URL] Only bid if you are capable of coding this. The last coder was not and has since disappeared when I told him it was broken. Lowest bid with the highest feedback wins this project.
