CiviCrm integration on Drupal existing site

CiviCRM is installed on our website, we need it integrated to Drupal. The main goals are: - Create an application form (with CiviCrm) for volunteers, this form includes custom fields I provide, this form allows the anonymous user to get automatically registered on the drupal site as "volunteer" so he can write his reports on a personal blog. The form includes an application fee (two separated amounts, one for the application one for the lenght of volunteering). We can discuss on weather it should be two separate forms or a process to be completed for the person applying. The form contains attachment fields which MUST be sent to an e-mail. - Create a membership page (four types of members: individual supporter, business supporter, student supporter, benefactor) with each including a diferent amount fee, renewal and description (Civimember). The members applying get automatically an account to the drupal website. - Create a donation page (with CiviContribute). The application forms, etc must be accessible to the public. The site is multilingual (english, french, spanish and german) so there must be the possibility of internationalize all contents created. The person applying for this project must have sufficient experience and proficience with CiviCrm and Drupal integration. The website is on a shared host, communications are maintained by e-mail. Only apply if you understand the goals and you are comfortable with the software cited above.
