Signing of PDF file

Hello There
We are researching a pdf processor for purchase. Following is what our web application need.
1 . One user of our site will put a placeholder for signature in the pdf document.
2. Later another user will actually insert a signature( or sign ) the pdf. At that time
the place holder should be replaced by the signature image.
The whole application is on web

Can this be done with aspose pdf? Please advice.
