Content migration between 2 Drupal 7 sites

Hi there, I am looking for an experienced Drupal developer to migrate content between 2 Drupal 7 sites pretty much with the same structure. Basically, there are 2 content types with 19 fields each: 1.) Articles - 941 nodes 2.) News - 238 nodes There are also 166 comments related to their respective nodes. Migration should include the following • Keep text formats • 19 fields use per content type (pretty much the same fields used for both) • Main image (Image field) and in-content inserted images (Image picker) • Taxonomies and proper categorization • URL paths should remain the same (older site will be 301 redirected to newer site) • Tags used in meta tag module and page title module • Keep authorship link to author’s account • Keep date of publishing • Anything else needed for proper migration. I look forward to getting your proposals. Thanks P.S.: We speak Spanish and Russian, so feel free to send your proposal in either language if you feel more comfortable. Regards.
