Website Tidy up & Health check

I have a Joomla site using a Gantry template. The site has approx 15 pages, an online store (only a handful of products) and a membership / login service. The site is [login to view URL] I need the following completed to tidy up the site. Change the main background colour of the browser window to white. I just cannot get this working form the template. Fix up the registration page (this is using the OSC member module) - currently this has some errors and does not work. I also need this to have a different layout so it asks for first name, last name, password, verify password, email address and a capchta box. I need all new registrations to be placed into the free membership group, so I need the drop down member group box removed and the promotion code box removed form the registration page. I would also prefer some better looking buttons rather than the standard grey ones currently in place. I would like to work this so that once a user completes the registration page, it adds the new member to a free membership group from the OSC module (this will give them access to a free member services page) and then integrate the registration to a get response subscriber list and send a confirmation request from Get response. All subscriber emails and newsletters will be managed from get response. Once the user is registered as a free member to the site, they can then buy subsequent subscription and education services via the online shop. I already have this set up so they gain access to the relevant pages linked to each subscription service. This is managed via the OSC / virtuemart integration. I need the members menu to only show the menu items that the user is a member of - this is currently working, but may need it checked. Also make the member menu a drop down when clicked - currently all items show on the member menu. Log out only seems to work from the home page - so need this fixed. When you click on the 'Free Member Content' button, the page loads, but the main menu disappears from the page - so need this fixed, so it behaves consistently as with the pages and always shows the main menu. Perform a general site / template health check & tidy up to ensure all sections, content, articles, menus and access levels to menus & web pages based on membership are working correctly. I also need the 'not authorised page' to look like something in keeping with the overall site theme - currently this just shows the generic text, not authorised etc. Jazz up the look of the menu colours & fonts (they look pretty dull at the moment) Add some basic SEO to each page. Add a footer with small font text that will contain a general disclaimer warning One of the main menu items links to an amazon a-store that I would like to run as an i-frame within my main site. I currently have this set up as a wrapper, but this does not fit in the main template, so I need a separate page template for the bookstore so that the Amazon site fits correctly. The main online shop is using virtuemart, with OSC management integrated to manage membership purchased and subscriptions for various education services. However currently the 'shopping cart' shows on all pages. I only want this to show from the Shop, so assume this requires a separate template for the shop. Need to be able to add downloadable media items to shop products. I cannot get this working I need the shop templates set up, so emails, purchase orders etc. are sent with the correct subject lines and text and a company logo etc. Any other tips or ideas welcome to improve the look & feel of the site. Upon successful completion of project - keen to retain the relationship for ongoing minor maintenance and assistance with the site. Site is currently hosted and running, so I can provide backend logins. Milestones: 25% to start 50% upon task completion 25% upon site being tested as fully working. If you can complete this in under a week I will pay a bonus
