C# Verifying digital signature in .xlsx and .docx files

I need one web application developed in c# (ASP.NET), using only classes from .Net Framework API, without use of API of other commercial companies.

Description:

Necessary files are .xlsx and .docx files (MS Office 2007 and 2010)

The user should be able to choose a file with FileChooser.

After choosing of a file:

--- if a document does not contain a digital signature, the program should report about this to the user (Warning).

--- if a document contains a digital signature, the program must read data of digital signature and of Certificate and must inform the folowing data to the users:

1) Who signed the document;

2) Date of signature;

3) Which organization issued a certificate;

4) Validity of a certificate;

5) Status of the digital signature

I want to buy SourceCode of this web application. The SourceCode must be written clearly and distinctly.I want to integrate this web application into my website
