PDF e-signature software using topaz signature pad

Develop a simple e-signature portal using topaz plug-in ([login to view URL]). All we want is a software where we can import pdf document and get it signed using topaz signature pad and save. We can get pdf signed in adobe acrobat also [login to view URL] But problem is its 5 step process, you have to open sign, then select method, then sign and finally place it. We want to keep it in one step once we import file and it automatically highlight signature line on pdf and once person signed it pass to next field. For your reference image is attached with highlighted signature field. Also there is a V-docs software in market which does same stuff plus upload signed pdf to server. We can skip uploading part but need 1 click solution to sign pdf files. Let me know if you any questions. Thanks Milo
