Drupal website

I would like this website, designed,developed and the same functionality of the reference site how it scrolls between pages being selected. [login to view URL]> I will be making some changes to the current site. 1. We will be adding another page SEO PACKAGES that will be needing a shopping cart linked to paypal, same design style as the other pages. Plus a slight change to the home page layout 2. I will be changing the color scheme and will attach the color chart in PSD to replace to the current colors gold and blue and the backgound color, I would still like the background texture however for the lucky winner 3. I will need a full administration, to add or delete any content loaded onto the site on any of the pages. In the admin anywhere we are able to write content there must be a character limiter and character count. All content areas of the web pages will be templates. I will just fill them out and submit. Meta tag and description box in the admin. Social Media FB, Twitter Paypal api key etc... The admin will also need to save client details as registered users: *Name *Address *Email *Telephone number *URL *Current status on Google, bing, yahoo etc *FPT password and User name *Admin User and Password *General information or comments *Terms and conditions pop up window (This will be the registration form when purchasing a package) 4. Incorporate a custom FB like button on the page and a Twitter follow button. 5. Contact page will have a few more questions on it. What is your URL? What is your monthly budget I Look forward to hearing from you.
