Hello,
my name is Josef, i'm experienced Drupal developer and administrator, and i would like to offer you my services. I have upgraded various Drupal 5 websites to Drupal 7, therefore i know exactly what's need to be done and how to do it. The problematic part is usage of modules, that are not supported in later Drupal versions, therefore i need you to contact me by private message with list of the installed modules (if you don't know how, i can give you instructions), so i can analyze the situation. I hope you will pick me for this project, and i'm looking forward to our cooperation.
Kind regards,
Josef
