Create a Custom Toolbar Using Alexa Features & Our Search Box

We need a custom built toolbar that we can offer our users. This toolbar must have our search box built in and we would also like it to use the Alexa system to so the Alexa ranking and at the same time help increase our ranking at Alexa. Also other things we would like is to be able to control the links on the toolbar, like with the related links on the alexa toolbar we would like to have links that we show, not related to the site but just a updatable link list. If you can do this and support this for future upgrades/add-ons then please let us know. If its not possible to use the Alexa toolbar features or showing alexa ranking and increasing Alexa ranking still let us know if you can create a Toolbar on its own. Thanks, Stephen
