Mail Signatures

Hi all, first post on here so be gentle please! Is it possible to use AppleScript to handle the creation of HTML signatures. Ideally I want to check if a signature with a given name already exists, I guess that's easy enough. Delete it if it does. Create a new HTML signature and then attach this new signature to be the default for a given account. Any help, greatly appreciated. Regards, Dave.
