Create executable to download HTML file from webservice and configure it as an Outlook signature

Hi, I have ~ 100 mailboxes in Exchange online. I have built a web service that returns an HTML page (in browser) when I send it an email address as a parameter in the URL. The URL will look like this: [login to view URL]<at>[login to view URL] I need an executable that would run silently on client computers and will do the following: 1. Read the primary email address of the default outlook profile of the user running the executable. 2. Get the HTML page from the web service using the email provided. 3. If a valid HTML page was returned, continue to next step. 3. Set the HTML as the default Outlook signature if the current signature is different or if there is no signature defined. I need 2 executables: 1. Will configure the default signature to new messages only. 2. Will configure the default signature to new messages, replies and forwards. The result I will get is 2 executables + complete source code that I can compile on my own. This is a small project with limited budget. Please bid accordingly. Thanks
