Non-profit upgrade to static ip and ssl

We are a 501©3 non-profit with a free hosting account on dreamhost. We need to upgrade our security to protect online donations by credit card. Can we keep the free hosting and pay the extra for the static ip address and ssl certificate?

Yes. While you have a free non-profit shared hosting plan, you can still add and pay for other DreamHost services if you need them.

Thanks Andrew for the prompt reply. That is very useful info.
