Build a simple web application for signing PDF documents

Hi Freelancers, I need to have a PDF signing webapp built. The UI should be very simple, just text and fields as I have shown in the attached documents. The user will need to be able to upload a document, preview the document and specify where on the document it should be signed, and specify the email address of the recipient who will be signing it. Then the recipient will be sent an email with a link to sign the document. He can click the link and view a PDF document preview and sign it, as shown in the attached. [login to view URL] is the javascript plugin we will use to capture the user's signature. then it goes back to the original sender for them to sign the PDF Then, after both have signed, another email is sent with a link to the signed document. View the attached documents and please put the word SIGNPROJECT in your bid so that I know that you have read and viewed the files. Thanks! Please feel free to ask any questions you might have.
