Sorry, I can't recommend a company. I did look up your ink though and it's meant to last about 30 years. Archival is about 72 years and hopefully more.
It looks like to get true archival ink, you'll have to go with a third party ink and won't be able to use Canon's. If you do that, I'd be really careful to read on the company's reviews.
