Browser plugin

We are looking for a developer that will be able to program for us a plugin for 3 browsers - Firefox, Chrome and Internet Explorer. Here is brief info of what the plugin should do: 1. after the user installs the plugin he will need to input his ID code to an config window of the plugin 2. the plugin will have 2 main functionalities - first one to import all his bookmarks to our site - when the user clicks on this functionality he will be shown a tree view of his bookmarks with all folders and bookmarks and he will be able to check which bookmarks/folders he wants to have imported to the site. after he selects this all the bookmarks info (title, link, category) and the user's code from the config will be sent to a php script on our server (the php script will be done by us, so we don't need you to program it) 3. second functionlity - the plugin will create an icon in the users browser - when the user clicks the icon it will send the info of the current page to our php script - sending title and the url of the page and again his ID code from the config We need price and time estimation for each plugin separately (chrome, FF, IE). We also want to see samples of your previous browser plugins that you worked on.
