Build a custom object for document approval on Salesforce

Hello, we need a developer to build a custom object on Salesforce for document approval. The document will move to different stage in the approval process and be displayed via Kanban View. in stage one, the document is submitted, then the a different user will review and move it to the next stage for approval by 2 other users. then the next stage after the approval will be for the document to be auto sent out to for signature via docusign. Docusign needs to be integrated as well. kindly get intouch. Thank you
