Hi, i'm professional administrator and developer, i have strong knowledge of Drupal and all related technologies, lot of experience with similar projects (including various drupal upgrades), and i would like to offer you my services. There may not be some module available for Drupal 7, so we will have to discuss the details during the project (there can be replacements, or i will have to patch them). If you have any question or more information, don't hesitate to contact me by private message. I'm looking forward to our cooperation.
