Add Dropdown Menu To Our Magento Website

Hi there, We need someone to add a dropdown menu to our clients Magento website. We have designs and PSD for the dropdown menu, we just need someone to code it in. We also have set up a testing development website so you can start right away. What is needed is outlined below: 1. See images '[login to view URL]' for what it currently looks like and '[login to view URL]' this is what the dropdwon should look like. We need the Dropdown menu adding so when a user hovers over 'Categories' a dropdown menu appears 2. The dropdown menu will contain around 50 categories but we will add the categories from our end to save time 3. As you can see from the design, 'About' is moved from the navigation menu to the top so we will need this doing, also there is a new category 'Small Spools' where about us was, we need this doing also 4. The client will add all products to the categories so don't worry about that Hopefully this should be a very quick job for someone who knows what they're doing. Everything is set up and ready to go! Any questions just ask. No time wasters or people who haven't even ready the brief. Thank you
