Wordpress with data forms, file upload and PDF creation

We have a Wordpress site that allows clients to submit financial information and upload documents of different types (PDF, JPG, DOC, etc.). We need some advanced features now to finish the site. Please take a look at the site. [login to view URL] Username freelancer Password Freel@ncer - there are 2 sections. The "Modification Interview" is using Gravity Forms to collect personal and financial information about the user. It does very simple calculations and displays an analysis to the user at the end. Document Management is a place for the user to upload different documents. When they have uploaded all of the required documents we need the site to combine all of the documents and create a single PDF file with watermarks on each page. I have purchased a license for SetaPDF ([login to view URL]). Some important features: The user should be able to return to the site at a later time and resume data entry without losing data. Tooltips can be displayed on any field. If the user has already uploaded one of the required documents it should show it, and allow them to delete it if necessary (example here [login to view URL]) Files can be uploaded one at a time. Admin can search, view and edit data and uploads from all users. If you have questions, please let me know. This is high priority and needs to be finished quickly. Thank you!
