Customise and populate existing Drupal 6 Template

We are a small software company about to launch a new version of our product. We would like someone to customise and populate an existing Drupal template to fit with existing images, movies, and words from our old HTML website content. We have already purchased the Drupal 6 theme from a template company. Notes: * We are a software company * We need a 'Download Now' button designed in the same style and added to the template * The Product page must provide same style placement for images, movies, and words * Shopping cart/eCommerce is handled via another website so you are not required to implement this, but we will need you to embed a virtual storefront * We need links to support and forums * Some new buttoms and integrating our company logo into the theme * We want to use Polls * We want to use the Google Analytics and SEO modules at some point * We want to maintain the website ourselves, so it needs to be set up to allow for this easily. We will supply words and some images
