Thawte has something for free (a personal certificate), but I don't know if it would detect tampering. That is usually done using some combination of PKI and a message digest (like MD5).
You need to make a list of what features you need in standard security terms and then do the research. I believe that most of the technology is there for the asking. You may even be able to set up a local Certificate Server to issue certificates to clients.
I found it interesting that you didn't mention Non-Repudiation. Is that something they even know about? It is considered to be important to e-commerce.
